I'm not disagreeing with you, but just because Staal is big does not mean he will be good infront. Look at Dino Ciccarelli. He was maybe 5'10" - 175lbs and he was very good infront. Playing infront is an art.
Staal's had some good ones to learn from... LeClair, Roberts, even Malone. I thought Staal's done well in his limited time playing in front of the net on the PP. I think I might have said it in this thread, or maybe it was in another, but I think probably the biggest factor in moving Staal to second line wing is to allow him to be able to take on a full PP load and totally fill Malone's role. I remember last year their reasoning for not giving Staal more PP time was that they didn't want to have their top three centers all on the same PP unit. If he takes well to being the big man in front of the net, he really could have a monster year.
