Thing is, people go to churches everyday asking for money- usually it's "I need some money for some food for my family" or whatever and I guess churches aren't required to keep track of where their money goes since it's supposedly for "a good cause" anyway and the church typically doesn't ask for the money back.
All you have to do is find a minister that's a die hard fan of a school and willing to hand out the money. And I'm sure they are out there. Football recruing isn't addressed in the Bible as far as I know, although Jesus did trash a bunch of money changer tables in the temple, so I'm sure it wouldn't be looked at very favorably.
It's brilliant because it doesn't look suspicious, and more importantly you don't have the paper trail, and you drag Jesus into it. I mean, who is going to question people getting money from a church?
