For anyone who wants Gruden, let me share some insight with you. I've been a big Bucs fan for many years and followed the team religously throughout his tenure. Gruden would be a terrible choice imo due to the demands he places on his QB's.
Gruden's system is incredibly complex and requires the QB in it to make many reads at the line and be a second coach on the field. If Tavaris (or Webb) will be the starting QB next year, they would die in Gruden's system. See Chris Simms and Bruce Gradkowski for more insight on this.
Granted, neither would ever be confused with a dependable NFL QB and I would rather have T-Jax running my offense than either one, but the point is that while Gruden is a solid
coach, he's not really a great
teacher. His system is dependant on the QB knowing how to adjust to the flow of a game, something which I'm doubting Tavaris would be able to do and Webb def. wouldn't be able to - at least not right away.
This is the same reason why veterans like Rich Gannon and Brad Johnson thrived under Gruden while the aforementioned younger guys struggled. As fun as his intensity would be, it would be overshadowed by his brutal demands on his QB's - demands neither likely starting QB next year would be able to meet.
I

Gruden and always will since he brought my Bucs a Super Bowl, but he's the wrong coach for MIN imo due to his inability to develop the most important position on the field. A Gruden-coached team needs a guy in this position who is already established as a veteran starter.
