Thats what happens when you play a skilled forward in your bottom 6, less ice time reduces their overall productivity and ability to get into the game, and playing with actual bottom 6 forwards creates less scoring opportunities for the guy. We got a gem, 30 goals isn't out of the question for MacArthur.
I am very glad the Senators signed him as a UFA. I think Toronto made a big mistake letting him go. And I also think Carlyle is one of the reasons he left the Leafs. Burke may have been a factor too. We need more players like him: fast, quick, backchecker, forechecker, puckhandling, drive to the net, good shot, enthusiastic.
I think Hoffman is developing nicely and might turn into a similar type of player.
