Church struggles in coverage. Killebrew may struggle with NFL receivers but will be better than Church covering TEs and RBs. Not sure what tape you'be seen but this kid is not only fast but fluid in coverage. And is a better center fielder than Wilcox will ever be. Instead of lacking a position, Killebrew can play multiple spots IMO.
Church doesn't play center field and I agree, never should, so that's not really pertinent to the argument.
However, I disagree about Killebrew's fluidity. He looks very stiff to me. I have watched everything I can on the kid and against lower rung NCAA competition, he looks pretty good in comparison. However, I don't think that is going to translate to the NFL. I don't think he has the movement skills to run with NFL receivers (be it wideouts, TEs or RBS), which why I think many people are projecting him as an undersized linebacker instead of a safety.
If he comes out and kills it in the shuttle and cone drill at the combine, I will be happy to change my stance. I like him as a player, I just think he's in for a tough transition when his athleticism isn't so much better than everyone else's.
Also, the Church hate is so casually common here now, that no one even bothers to actually watch tape and get into the numbers. When you do, it's pretty clear Church isn't the bum so many here want to make him out to be. It's just easy to jump in with the negative group think. He has lost some athleticism and it's definitely time to start thinking about having someone behind him, however outside of a miraculous performance by a rookie, I don't think anyone supplants him this season. Not full time at least.
