The quarterback position was a big mystery when Michigan commenced preparations for this football season.It is now one of the teams biggest strengths thanks to the stellar play of sophomore Wilton Speight.Speight has exceeded all expectations and attempts to help the No. 3 Wolverines (9-0, 6-0 Big Ten) remain unbeaten when they visit Iowa (5-4, 3-3) on Saturday (8:12 p.m. ET, ABC).The 6-foot-6 Speight outlasted Houston transfer John OKorn in a competition that began in the spring and continued through late August.Once he landed the gig, Speight responded with consistently good play, topped by last Saturdays 362-yard passing effort against Maryland.Hes superseded the hopes, hes gone past what we were hoping hed be -- in a big way, coach Jim Harbaugh said in a press conference. Hes been outstanding. Outstanding. Id be lying if I said he hasnt done more than what we hoped hed be this season.Hes met the challenge at every pass. Hes acquitted himself more than good. Hes got a hot hand and its come through preparation and its been really important to him. And thats really why you dont put expectations on people and you dont limit what you think they can be.Ironically, Speight considered transferring prior to Harbaughs first season after being berated by coach in the spring of 2015.The segment aired in an HBO special. Speights face and jersey number were blocked out but there was no denying that a really tall quarterback was told the following:If you want to look at me with that look, go (expletive) somewhere else, Harbaugh barked.Speight and his family investigated leaving before he decided to remain with the Wolverines.That redshirt freshman fall camp, I was on the phone with my parents basically, OK, Im out, lets find a different school. They were on board. They obviously wanted me to stay here, but they were going to support my decision.Things are working out well now for Speight and Michigan and he enters the game against the Hawkeyes with 2,053 yards and 15 touchdowns against three interceptions.He will look for more production against an Iowa squad that is reeling after being pounded 41-14 by Penn State last Saturday.The loss was the second straight for the Hawkeyes and a humbling one for coach Kirk Ferentz.We got hit right on the chin, Ferentz said in a press conference. The whole challenge is to get back up on your feet and go back to work. We have to do it this week because the team we play is going to be a big challenge for us.Iowa is just one game off the pace in the Big Ten West despite its recent struggles. An offense that has topped 40 points on three occasions has suddenly gone dormant and combined for just 23 points in the two defeats.Senior quarterback C.J. Beathard has passed for fewer than 200 yards in six of nine games. His 204-yard effort against Penn State matched his second-best output of a season in which he has thrown for 1,584 yards and 13 touchdowns against five interceptions.The sharing of backfield duties by junior Akrum Wadley and senior LeShun Daniels has been a strength. Wadley has rushed for 664 yards and eight touchdowns and Daniels has 642 yards and six scores.The defense was gashed for 599 yards by Penn State -- a staggering amount with stars such as senior cornerback Desmond King (12 career interceptions) and junior middle linebacker Josey Jewell (Big Ten-leading 87 tackles) headlining the unit.I think you try to keep people motivated, coming in every day and giving it their all, Jewell said in response to a question about a possible leadership void. Thats what we have to focus on now.Michigans defense has had few issues all season long as the unit leads the nation in scoring defense (10.7 points per game), total defense (246.3), passing defense (138.9) and third-down conversion defense (19.0).Sophomore outside linebacker Jabrill Peppers has fueled the success with a team-best 13 1/2 tackles for losses. Senior middle linebacker Ben Gedeon has been consistent all season and has a team-high 74 tackles while senior cornerback Jourdan Lewis (two interceptions) is in top form after early season injury issues.An offensive player performing well is senior tight end Jake Butt, who became the schools all-time leader for receiving yards (1,521) by a tight end in last Saturdays 59-3 trouncing of Maryland.The Wolverines have lost in each of their last three visits to Iowa so nobody is taking the Hawkeyes lightly.Iowa, this is a championship (game), and we take that to heart, Speight said. We know its win or go home. All this means nothing if were 9-1 this time next week. Jeff Bagwell Astros Jersey .

Newcastle dominated in the early stages but City weathered the storm and then raised its game in extra time. Negredo broke the deadlock from close range after a simple move in the 99th minute before Dzeko took the ball round goalkeeper Tim Krul to seal the victory in the 105th. Carlos Lee Astros Jersey . -- Nate Robinson has played for seven teams, so beating one of them is no longer a rare occurrence. George Kruis is available against Argentina on Saturday with Eddie Jones considering his immediate return to Englands starting XV.Kruis has missed the autumn victories over South Africa and Fiji after undergoing minor ankle surgery and his club Saracens estimated that he would be sidelined for four to eight weeks.The second row, an ever-present under Jones until injury struck, has made a rapid recovery while ensconced at Englands Surrey training base and Jones must decide whether to break up the Courtney Lawes-Joe Launchbury partnership that has served him well so far this autumn.Kruis is probably going to be available - hes fit and ready to go. He doesnt necessarily need to play for his club first, Jones said. Its not necessarily better to bring him off the bench. You talk to the players and they like to play with the best players at the start of the game. Well wait and see.Weve got great competition in there because Launchbury and Courtney Lawes have done superbly for us.Neither Joe nor Courtney had great training weeks. They both had ailments that clouded our selection a bit, so their efffort against Fiji was good.ddddddddddddJones has already pencilled in his starting XV to face Argentina at Twickenham with Mike Brown set to return at the expense of Alex Goode at full-back.I think I know the team, but its always up for grabs. The players have until 2.20pm on Saturday to get picked! Jones said.A few players may have clouded it a little bit after the Fiji game. I thought Elliot Daly was good on the left wing.Whether thats his best position, Im not sure, but it certainly worked. I was pleased with him and with Jonathan Joseph, whose defence was absolutely outstanding.Jonny May has had a good training week. Hes definitely fitter, definitely ready to go. And Mike Brown is in good nick, so theyll be back competing for selection.When asked about the duel between Brown and Goode, Jones replied: Where do I see it? Intriguing.Theres always one above the other. Its like life. Someone is always above the other. Youll find out when I pick the side next week. ' ' '
