Leafs can afford Tavares.
It will be a very tight fit, if he decides to come to Toronto. But it's definitely possible to fit his $10 million salary on the team.
But for the team to have success, they need players on ELCs to step up every year. So lots of pressure on Mark Hunter.
Also, like people have pointed out JVR, Bozak and Komarov are out. But so is Gardiner. As on next season Leivo, Aaltonen, Kapanen, and Grundstrom are all ready to step in. On defence they have Travis Dermott ready to step in and play as well.
