Or bad, depending how you look at it (speaks to their C depth)
He is a great option to have on the Leafs as a 13th forward next year. Rather him than some vet without a future. I do not remember a single time he had a bad game in the Marlies playoffs, and he looked like he developed some offensive competence as well. He's never going to light up a score sheet, but there should not be anything stopping him from producing a normal 4C rate in the NHL if he is given the right line mates and opportunities to do so.
Plus, he still has value as a trade chip. Maybe not a ton, but there could be a team out there that likes a big, cheap 4C with some upside left in the tank.
