There's some ideas in this thread that I would humbly suggest that people should stop arguing:
1. Kill doesn't have enough of a track record to show that he will succeed at Minnesota. This is true but it's a tautology. It's like saying the team with the most points will win the game. Of course we don't know if Kill will succeed - every situation is different. That said, he's our coach now, so why worry about if his tenures at SIU or NIU or wherever conclusively show whether he will succeed here or not? They can't do this one way or another. We will know within another 2-3 years whether Kill can build and coach a winning program here and (hopefully) in the following 4-5 years whether he can sustain it. Looking to his past coaching stints can provide clues to how much success he'll have here, but nothing close to any definitive proof or evidence of what he'll do here.
2. Brewster was a great recruiter who just couldn't coach X's and O's. Now, I don't believe anyone came out and said "Brewster was a great recruiter" in this thread, but someone highlighted some key players (Gray, etc.) that he brought here. All well and good, but if you go back and look at his actual recruiting record, a big percentage of his top recruits never came here or didn't work out or whatever. I hope Brandon Green does great this year in his Sr year, but for a 4* recruit, he hasn't produced a lot in his first years here. As others have pointed out, Michael Carter was a big recruiting coup who is similar to Brandon Green in terms of production - I hope he has a great Sr year for us. Other top 4* guys Brew brought in - Sam Maresh, David Pittman (I'm sure dpo and others could quote the whole list) were complete busts or underachievers. Brew seemed to care a lot about the number of stars by a recruit's name, regardless of if they would turn into star football players. So please don't tell me (or imply) Brew was a great recruiter - he had one good class on paper that turned out to be a lot thinner than it originally looked.
Which brings me to what we all should've learned from the Brew era - I would much rather have a coach Kill, who has a system in place, a coaching staff in place, schemes in place and an idea of what type of player he wants to win and the confidence to recruit those players regardless of how many stars Rivals or Scout or ESPN "gives" them. Yes, he has never won at a BCS level before - he could fail at this job - but I'd argue he has about the best track record possible for anyone who would realistically accept a Gophers job. For those lamenting him bringing in "MAC-level talent," just note that - with 100% "MAC" talent - he went 2-3 against B1G teams (same winning percentage as sainted Mr. Mason), scoring exactly as many points as the B1G teams in those 5 games, all of which were on the road. Again, this doesn't prove he'll win here, but it does show us he's done well with less elsewhere - which is exactly what any Gophers coach will absolutely need to do if he is to be successful.
