Begin and Higgins showed good chemistry during the regular season. Higgins is just a good versatile player. He can play on any line, with any center. The key is to get Ryder to mesh with Begin and Higgins off the cycle. They'll be able to dig the puck out of the corner. If Ryder gets dirty in front of the net, he'll get his chances when they throw it at the net.
Some questions were meant to be asked but not answered. My theory is that, according to quantum mechanics, even though he does not have the necessary skill to be a top 6 winger, he has a non-zero probability of "tunneling" into a that position.
