I may be in the minority, but I'm sure Becht knows way more about these camps than anyone here. Players don't care about these camps that much. Remember when Johnny Manziel was (allegedly) drunk at Manning Camp a few years ago?
Geno had a legit excuse to back out of the camp with a death close to him. If IK was giving him the silent treatment at camp because Geno backed out, then he's just completely immature (as proven by the punch).
