You are spot on in your analysis of Seastrunk. He is a prima donna. He likes the attention. He definitely is a better fit at LSU or USC with his personality. Would I take him though? Hell yes.
I've never felt that way about Seastrunk. He's kind of a class clown personality, loves joking and having fun, but in the live interviews I've seen (and from what coaches say, including Saban), he's a very, very respectful (yes sir, yes m'am) kind of kid.
He takes his relationship with God and his parents very serious, and while he's kind of a crack-up, fun loving kid, I don't get the impression it's out of being self-absorbed or thinking he's above anyone or anything. When he got invited to play in that elite group in Florida, he went on and on about what an honor it was to be selected. He didn't go on and on about it being a an opportunity to "displaying my skillz for everyone to see how great I am", which is what you get from a lot of kids these days.
Anyway, I really think he's a character, but not in a bad way.
