No, I don't think they have a chance. They are still very poor tacklers in space and besides the Hein kid, they have no real playmakers on offense for the big stage. Coach K's son is talented, but I would only classify him as a "good HS RB." Its really incredible how few good skill players they have.
I've heard a ton of stuff both ways on this. I am leaning toward thinking he will quit. (I've heard good sources about the rumors mentioned in the other thread but can't believe it...) He does have another kid in HS at Mars so you never know. I don't think there is any way he goes anywhere besides of P4 school (Pitt/PSU/WVU) because the salary differential would be way too much. He's gotta be a 25+ year teacher at NH making north of 100k.
On top of this, his son is going to play in college so he may want to watch him.
But, ya, the story was there 1-9 before he got there, to 6-5, to 10-3 and a win over Central Valley, to what will likely be a 5-6 season.
