I'd rather have Markov doing that than either. And I'd take a highly graduated student of Markov over Weber any day. More complete teachings, especially when it comes to puck retreival, transition passing, handling traffic when carrying, how to carry, securing control in the o-zone, keeping the line in the o-zone, displacing the opposing d-box and well, pretty much anything that has to do with passing and playmaking. I want complete dmen, not just guys who can shutdown.
Oh yeah, Weber might be a bit better at some of the defensive aspects, but I find him wholly lacking in all those things I've named.
