I would not be in favor of signing him to The Colts. This has nothing to do with his kneeling or social justice work; I just don't think he's the right kind of QB for our scheme.
Personally I think he was a decent QB in the right system, but he doesn't seem to me to be the type of QB that can thrive in any system, and more specifically ours. Add to this the fact that he has not played for several years and it's a hard pass for me.
I, unlike others, wish him no ill will, and hope he is successful & happy in life. However I think our QB room is better without him.
My thought is that enough time had passed - prior to the George Floyd incident - that he would have been brought onboard if he actually had better talent than those already in the league and those who would come cheaper. That's my .02 without making this too political. There have been other talents in the league with marks against them that have been added to rosters because their talent was worth the bad press. I would suspect that having the best talent on the roster is the highest priority to some owners - regardless getting some bad views from the press or the fans.
I like our QB room right now. No need to add Kaep.
