I honestly don't know at this point, but I'm leaning towards no. It's year 5 and his team regularly implodes at inopportune times, can't do simple things like hold a snap on a FG, and struggles (loses) with Northwestern at home. Sure, he's lost some players to injuries, suspensions, and attrition, but I don't think he's done a great job at adding depth along the front 7. It's year 5 and there are too many times where the opposing team is able to run the ball down our throats and there's nothing we can to stop it.
He routinely makes questionable in-game decisions, seems to sit better players in favor of lesser ones (i.e. Redfield), and seems to have a hard time at adding good depth at needed positions (particularly along the defensive line).
He's the best coach we've had since Holtz, but that says nothing, because it's not hard to be better than the previous three clowns we've brought in (okay, Davie wasn't a clown, just overmatched). It seems like the overall talent level is better now than it's been in a while too. At some point however, you have to start seeing results. We've lost 4+ games in now four of the five seasons he's been here. ND did not hire him to lose 4+ games four out of every five years. That simply isn't debatable.
If he fails to win 10+ games next season, with the returning talent ND should have coming back, then I want him gone. He needs to hold onto the guys currently on the team who could potentially want out for various reasons as well. ND has had far too much attrition since BK has been here. At first, you think it's a coincidence, but then you start to wonder if maybe BK has something to do with all of the attrition we've had.
10+ wins next season or bust.
