Great grab. Believe me, you will start getting trade offers for him very soon. I have sat on MAB all year and now it should pay off big time. The guy is pure offense. 42 goals and over 100 points in his last junior year as a D man?!?!
He has a history with coach Boucher (6 pts in 3 games) and will fit in very well with TB's system. He will be used pretty much exclusively on the PP and should do what he always does - put up numbers. He is extra valuable in leagues like yours that do not count +/-. He is in pretty much the perfect situation and I think he will be utilized very well in TB. Look how great he did last year in pressure packed MTL.
I can see him getting 8-10 goals and 15-20 assists if he thrives. Should really help you if you are contending, and could be a real nice asset to move to a contender if you are not. Either way, a very nice grab.
