That's the problem, many can't separate the two. He inherited something bad and made it much worse. And because it was so much worse so quickly, people said "but he inherited a co Big East champion!"
Ask Coach P was he thinks about inheriting Big East champions.
Is that directed at me? Because I have no problem separating the argument. I think GRob was an ass clown of a coach who came in and tried to implement new systems on both sides of the ball that sucked, and the team's performance plummeted. I also believe that he had way more talent on that 2005 team than 1-10.
And yet, he came in spouting off about having the talent to compete for national championships in short order, and that all the new coaching staff needed to do was implement a new offensive system for that to happen. You know--kind of like the same thing that lots of posters are clamoring for now to have everything magically improve.
It's all about the talent, no matter what system you run. GRob couldn't get it done on the recruiting trail with QB, WR, TE, or OL, so his crappy systems never came together. So far, Marrone hasn't recruited an impressive array of skilled players, either [although he appears to be doing better at WR, TE, and OL], and it remains to be seen whether he can get the job done--despite landing Thompson / MacFarlane / Cornelius, and potentially a Perkins / Morris / Lynch. [as an aside, I omit QB even though we have some prospects in the pipeline [Kinder, Hunt, Broyld] as I stopped being optimistic about our QBs about 10 recruits ago--I'll believe it when I see one of them actually pan out]
Edit: before Bees comes after me for taking a shot at GRob, I readily acknowledge that he was a nice guy and a class act. But he was a natural disaster of a head coach.
