I would prefer someone on the right side of 40. But to answer your question - if you can sign up for AARP - 'old man'.
so Saban and Meyer are out on your criteria???...
Age is one thing, energy level and effectiveness are another.
I think you need to re-evaluate your criteria.
I'll take anyone that can recruit, coach, develop, and put together an effective game day strategy, and then get some wins.
If they can do that for 5 years or so, even better.
My concern with a young coach is that any success will get them an offer somewhere else. And Uconn needs some stability.
What Uconn needs is an 'experienced' head coach, maybe someone with NFL experience. Preferably someone with good connections to the CT high schools. And, if he had an idea for his OC, even better.
