Wishart vs Alzner. Only 4 months difference in age. Karl is supposed to be top 5 material and Ty was picked at 16 last year. Both have good size and can put up some points on the board. Wishart has been on fire of late (13 pts in his last 13 games). Which defensemen has better pro upside? What type of game do they play? How far away do you think they are?
