as I said, if I was his advisor I would tell him not to sign, but going back doesn't mean he won't sign just hard to see how much better a situation it would have been for him with Chiarot injured. That said there's no harm in getting your degree, he does need to add mass and strength.
As for people saying trade him to the preds, there's little hope of that imo, unless he agrees to sign with them right away as they could be losing the BEST D prospect in the NCAA in David Farrance, I don't think they want to take another gamble without him agreeing to sign now. He would be a very nice replacement if they were to lose Farrance, which the rumors are they will cause he wants to sign with NYR but we'll likely find out more in the next week or two depending on how far BU goes.
But this also sucks for Struble, unless they put Harris back at RD next year, Strubble will be 2nd fiddle to Harris who will be the captain and likely top 1o finalist for the Hobey Baker.
