Mauer was going to play Baseball for FSU too, and for reasons that are mostly geographical (weather) the Big Ten is basically a Mid-Major Conference in College Baseball. Beside, usually if guys are relatively equal prospects in Baseball and Football, they almost always choose Baseball.
But no one should hate Seantrel. An 18 year old should be allowed to go to school where he chooses. There are some villains here though. First, his dad seems like he's squeezing every little bit of attention he can get out his son's talent. Second, its pretty Hilarious that that McKinnie couldn't make it to Pro Bowl practice because he was too busy convincing Henderson to leave his home state at some Miami Club. That's pretty disrespectful to a lot of Minnesotans and Vikings Fans since obviously there is some cross over on the fan bases. Also, what the hell is a high school kid doing in a Miami club? I know this stuff always happens, but usually their parents are stupid enough to talk about it. Maybe a Gopher Beat Writer could take a little vacation to Miami and investigate.
But I think there is a bigger question here, why does virtually every high rated prospect from Cretin Durham end up going somewhere else? Mauer, Floyd, Henderson, etc. First they steal the best high school kids from other schools, then they convince them to leave the state for college. CDH has a great football program, but they certainly aren't helping the overall state of football in Minnesota.
