I revere Vesey's play about as much as anybody on this board. Despite how good this season was, I still think it falls short of what the '88 team did in a number of important ways. That team won a league championship. Sure, it was Division II, but that was the division they were in. They won it. They also won a round in the NCAAs, and this year's team didn't manage that. So there are still steps left to take.
However, the knock on Vesey that likely ended up placing him at Merrimack, and not at another Division 1 school at the time, and was really quite visible in his short stint with the Bruins, was his skating speed. The game and his linemates were going on ahead without him, and being behind the play meant that his vision, his hands, his shot, and even his strength in the corners, rarely became factors. He was a much more complete player at the AHL/IHL level, in great part due to the slower speed. I'd argue that the NHL, the AHL, and Hockey East are all faster-moving, faster-skating leagues now than they were back then. I think Vesey certainly could make this year's team, and be an imposing force-- but more so than back then, the way his line would play would have to be built around slowing the game down.
I think, in the end, a team is better off building around a fast-skating, puckhandling playmaker like Da Costa than they are around a hard-nosed power forward with good hands like Vesey, especially at today's faster pace. The ironic thing is that I always thought Vesey's game was more suited to the pros than Da Costa's, but right now I think Da Costa has a better shot at NHL longevity than Vesey got. Vesey had the size and the hands, but not the speed. Da Costa has the hands, the vision, and the speed-- perhaps not the size, but there are other players of smaller stature who have stuck in the NHL because they have the same skillset as Da Costa does.
It's really hard to compare across such long periods of time. I suppose if I had to pick between 4 years of Vesey or 2 years of Da Costa... it's close. 4 years of Vesey vs 4 years of Da Costa, in today's Hockey East? I think I have to go with Da Costa. With a player like that at center, you don't necessarily need a Vesey on the wings. An Ingraham will do.
