Seems like he'd be worth developing since he's apparently successful playing big minutes against tough competition in Hockey East.
Who are their other defensive D prospects? Samorukov and Lagesson? Both Left shot guys.
All other right shot guys are more offensive (Bear, Berglund, Persson, Marino).
I suppose Phil Kemp is an intriguing right shot defensive d-man with size, but he could take a long time to develop. Desharnais is 3 years older and 2 full NCAA years ahead.
The Oilers aren't in a position to let valuable prospects walk, especially on defence.
