Personally, I'd draft them in this way:
Seguin - I just personally like him more then Hall. He'll be a better all around player.
Hall - the consensus number one pick. He's a good talent, but I just don't quite buy the top hype, and having seen both play, I just think Seguin will be the better player.
MPS - third best talent of the three. If he's actually gonna be available (I don't know why someone in you're league wouldn't have stashed him before the season ends, like I'm doing in mine), then he's an easy pickup. Just has top-end talent.
Eberle - has big name value, showed a fair bit in his first AHL game. Still not completely sold on his upside in the Show, but he's got all the makings of a solid contributor.
