One of the most controversial decisions of the college football season all but dropped Wisconsin out of the national championship hunt on Saturday night. Did Michigan States Keith Nichol break the plane of the goal line on a last-second 44-yard Hail Mary reception? Did Wisconsins defenders push Nichol back in the nick of time and force overtime?On-field officials ruled Nichols remarkable catch fell just short of the end zone. Replay officials, however, overturned the call, giving Michigan State the game-winning touchdown in a thrilling 37-31 victory against Wisconsin at Spartan Stadium.The call likely ended any national title discussions for Wisconsin (6-1, 2-1 in Big Ten play), which entered the game ranked No. 6 in the first BCS standings.As one might imagine, the Twitter world was abuzz with reaction to the big play late Saturday night. A sampling of those responses:Mike Pereira, former vice president for officiating in the NFL and FOXSports.com contributor (@MikePereira): Great reversal in replay. He did break the plane. That is great use of replay. What an ending. Replay has become such a big part of football. The big thing is that they got the play right at the end of the night.Jason Whitlock, national FOXSports.com columnist (@WhitlockJason): Hail Mary didnt end Wisky national title hopes. Bielemas timeouts did. CFB is awesome! Darren Rovell, sports business reporter for CNBC (@darrenrovell): I hate how on plays like this no1 can ever say We were lucky. They always say We practiced it. Off defensive player?Tim Dahlberg, Associated Press sports writer (@timdahlberg): State of college football: replay overturn could cost Wisconsin millionsKevin Kugler, Nebraska Cornhuskers broadcaster (@kevinkugler): Was that indisputable video evidence? I didnt think so.JJ Watt, former Wisconsin defensive end and current Houston Texan (@JJWatt): Ok, that picture obviously shows it was a touchdown. Good game State.Plaxico Burress, former Michigan State wide receiver and current New York Jet (@plaxico): There is a BIG party in E. Lansing tonight! What a game! Great game boys!! Spartan Nation is proud of you. Victory for MSU!!!!!!!Drew Stanton, former Michigan State quarterback and current Detroit Lion (@drewstanton): EL gonna be crazy tonight, enjoy all u that r up there. Congrats to Keith Nichols, couldn't happen to a better guy! victory4msu SPORTSbyBROOKS, national sports blog (@SPORTSbyBROOKS): One camera angle behind goal line & other in front of it. Nuts to decide any game wout clear evidence, let alone that one. The 2 cameras goal line views not linear. Impossible to know if he broke plane. On one cam he did, on the other he didnt.Steve Czaban, national sports-talk radio personality (@czabe): Right call. Period. Any opinion otherwise puts you in the Jeffrey Maier didn't lean over camp of replay deniers. One more thing: the whole concept of on field ruling having primary status is stupid. Doctors don't ignore x-rays for a reason.
