Your given a team in all the big leagues, you could pick whoever you want to manage them...
College Hoops- Jimmy Valvano best personality for a coach, next would be Pitino.
College Football- I'll take Woody Hayes we need more coaches brawling with players, some of these kids need to get tuned up sometimes
NFL- Tom Landry
MLB- Tommy Lasorda. If I had a veteran team I would go Joe Torre. Any of the old school guys who didn't take shit I'm good with; Sparky Anderson, Bobby Cox and of course Earl Weaver, for example youtube.com
NBA- Pat Riley
NHL- Al Arbour
Runner up for NFL would probably be Parcells and Ditka but players today would probably not be able to deal with their old school style, getting yelled at and all that.
