They got out ahead of the pack and made their big splash already acquiring Kyle Clifford as a depth forward.
Honestly, right now it feels like a pretty good mix of players, the team doesn't need anything and they have no cap room. Kerfoot and Bunting are producing like top-6 players. Until they start to struggle, I don't even really see the need to tweak for deadline prices.
If they do become 100% healthy, they will likely trade or lose Engvall on waivers like they have Amadio and Brooks so far. I knew coming into the season with an extra team in the league, that they might struggle sneaking their extra forwards through waivers. So, unless one or two of those forwards make their way back to Toronto, they may have to augment their forward depth at the bubble player level, like they did with Clifford. As Semyonov went back to the KHL as well. So, they're soon to be down 4 forwards, with only 1 brought in since the season started. They are going to need a couple more options.
Kivihalme hasn't been playing much for the Marlies and he is a decent AHL player, he could be bait for a forward. They could also give Ho-Sang an NHL contract and use him.
