That's great news for Buffalo. I became a big fan of McArthur's over the last two years with his play in Medicine Hat. He was stellar for Canada at the WJC's. I think he's one of the most underrated prospects in the game, and a potential second line forward in the future.
MacArthur should be an effective player in Rochester for a one to two year term. As stated before, strength development will be priority one, and in my eyes, keeping his cool and not getting goaded into stupid penalties will be on the list as well. He seems to have a temper, and has an affinifty for the misconduct.
