Are you concerned he cleans up recruiting or are you concerned he wins big there? I understand concern around his recruiting, but I don't understand any concerns about him being a big winner.
You don't hire someone to keep them from recruiting your territory, you hire someone because you think he is going to win games for you.
We only play them once a year so outside of the recruiting bump you get from winning we aren't really concerned with that. You worry that he will secure players you want.
I understand your point though that he shouldn't be hired if the only reason is to block Mizzou
