Don't forget that Dantonio has won like 8 straight vs Purdue after Tiller went 3-0 against Saban and I think 3-1 against John L Smith.
So many of them have been close, but MSU has made more plays to win.
I was surprised MSU is favored the way Purdue is playing offensively, but if Lewerke is truly out Purdue will truly have to have partied all week and not focused to lose.
I would bet Purdue covered a good deal of those. Remember Purdue gave MSU game after game when MSU was at it's best, and Purdue was at it's lowest.
MSU has a 7 game winning streak going back to 2007.
2007 and 2008 were comfortable wins, but the last 5 have not been.
2009, MSU got bowl eligible over a 4-7 Purdue team by ending the game on a 17-3 run to turn around an 11 point deficit with 11 minutes to go.
2010, a 4-7 Purdue team almost derailed 10-1 MSU's first Big Ten championship in two decades, but again a 22-3 run in the 4th quarter turned a 15 point deficit with 10 minutes to play into a 4 point win
2013, MSU's best team in a generation needed a late TD to go ahead 14-0 over a 1-6 Purdue team. It was 7-0 almost the whole game, thanks to a defensive TD
2014, 5-1 MSU got a pick 6 in the final 2 minutes, when Purdue had the ball, down 7, with a chance to tie or win
2015, MSU's CFP team raced out to a 21-0 lead, and hung on for a 24-21 win over 1-4 Purdue, who had the ball, past midfield late in the game, with a chance to tie or win.
