This is a legit use of age in evaluating coach. You hire a Calhoun at 40 or a Geno at 30 and you have some time to evaluate how their coaching matures and having 3-4 years of learning/progress then gives you a picture of what's up and if succeed you get a coach for 20 years. Not same for 61 year old guy. You expect he hits ground running, makes good short term decisions on schemes, coaches, players. This coach is not here be build a 25 year tenure. He is here to get it right immediately and set stage for establishing a program.
Age means he has a history to review. GD hurt him at Syracuse (per these guys) and per my perception has been the weak link here. RB's coach per my reading of what he said or didn't say is not on board with the LM only or wildcat. Is not a prior college RB or RB coach, GD has not improved the OL.
Why would I expect PP to get better as a coach when he has 40 years of experience from which to develop "muscle memory" and he picks GD, can't manage clock, players not prepared. An assistant coach up to head coach would be learning, not this guy.
Young and inexperience guy you evaluate "progress"; guy with 40 years of coaching and 10 years as college head coach you evaluate "performance".
PP has made minimal progress, if any, and performance is poor. Lose to Buffalo and ??????
Age means you have a history, expecting you to perform contrary/better than your history is quite the leap of faith and if that is what PP must do to be successful at Uconn then this was a very low % hire.
