I'm old too (55 yo), but it's not change I have a problem with - it's the rah-rah/hype train/juiced up thing that grows a bit tiresome...
I liked CPJ's approach to the game, the media, life, and so on... Straight-effin shooter... Been around long enough, you come to appreciate people of that sort... Yes, he was a bit of a curmudgeon, but with enough miles on the tires, that's what's usually happens... Thing was, he was almost always right, and he generally backed it up...
I really hope that CGC's enthusiasm and energy translate to bringing in better talent and fielding a more competitive team... Clearly, he's an upgrade from the previous staff in that dimension... What remains to be seem is his ability to coach football and compete with some of the best teams in the country...
I do know that I will miss the CPJ option offense - when it was working, it was a thing of beauty... Best I can hope for is that we run more of a Friedgen-style offence with a variety of formations and sets, including just enough TO tho shake things up...
