How is his overall game? I know he can shoot the puck.
I don't think Guy Boucher liked him as a player. Earlier in the season you can tell he tried to follow the "play my role regardless of where I am in the lineup" mantra as he was mostly stuck on the 4th line with Neil and Kelly. At times he looked fine as a 4th liner, but other times he seemed like he was lost in Guy Boucher's system. The Jokinen goal last game looked like it was his fault off of a bad decision in the neutral zone and maybe that combined with him not stepping up in what was an ideal situation with multiple top Senators injured might have been the last straw. Dzingel stepped up when MacArthur was hurt, and last game Lazar came back to the NHL after suffering from mono and being regulated to the AHL and made a greater impact than Puempel who has been around all season.
Ultimately, he is a complimentary player, a finisher. I thought all he needed was prolonged time with a guy like Brassard to get going, but I was probably wrong. He's scored at every level except for the NHL, so this isn't a bad pickup. A change of scenery, the right center, and a simplified role might lead to him finding his groove in the NHL.
This is a move that at this point had to be made, but there is also a small chance it could bite Ottawa in the ass if he takes well to a change of scenery and the Rangers figure out how to get him scoring goals in the NHL like he did in the AHL.
I'm not shocked he was picked up, but I'd be curious if there were any claims after the Rangers as they are pretty far down the waiver priority.
