I don't think it is very intelligent for an established college coach to attempt to go to the pros. In the college situation, the coach usually has almost absolute control over the situation. He/she can recruit to his/her needs and style. The practices and routines are established. The assistants and support staff tend to be selected by the coach.
If you go to the pros, you probably find that there is an owner, a general manager, a scouting director, and other parts of an organization that may have more control over the situation than you do, and you don't select them. They are imbedded by the owner. You may not even have the final say on the players that your team drafts. Your coaching decisions may well be impacted by an interfering general manager or owner. You are pretty much bound to work within the confines and constrictions imposed by the team management, all of whom will be there when you leave. Indeed, they'll likely be there through several coaches. You are this year's model and may have only two or three years to turn around a product that they are making the key decisions on.
For the most part, the carousel consists of a group of coaches who are willing to operate within these parameters, most of whom have one or two good years on which to base their reputation. Hopefully, it is sufficient since they may well never be back.
