In no way is this to be interpreted as a slam against that short article, but anyone familiar with Kelly's game time behavior is fully aware that the actions described in referenced article are not out of character at all.
Herbie might have had a problem with it, and even some ND fans may have been disappointed their coach behaved "inappropriately," but rest assured it did not surprise those in charge of the hiring or fans that have watched Kelly in the past at places like GVSU, CMU, et.al.
As a GVSU alum -granted pre-Kelly and still during the quarter system - I am fully aware of his game time persona, but not at all with how he conducts himself at practice and whether or not it's different than Saturdays. If not, then I'm sure the players have no more problems with it than they would on a Tuesday or Thursday and speaks more of how Herbie preferred to be coached and the difference between a Cooper and a Hayes.
ND has displayed enough arrogance in hiring inexperienced college head coaches, highlighted by the Faust hiring that was roughly the equivalent of promoting a corporal to a Brigadier General, bypassing approximately 15 positions in the process, that they knew something had to change.
I think their premature claims to a return to glory have been heard enough times in their AD's office that he has clearly received the message that sometimes they'll have to go outside the comfort level of alumni or subway fans to get someone actually capable of performing that feat.
As is the case with RR, I think BK will be just fine there in his head coaching duties, but again just like Rich remaining true to who he really is, ND fans and TV commentators will have to accept the fact that Kelly, albeit a very successful football coach, is an arrogant ass, and that's not meant as an insult either, but just to point out to people unfamiliar with Kelly just what type of personality he possesses. Believe me, it's not one that would compel you to invite him to meet the gang at Joe's on a normal Thurs evening.
