Vesey and Simmonds are both reclamation projects, in a sense. Both players were barely NHL worthy when the last regular season ended.
That said, I've heard nothing but good things about the health, prep, and attitude from both of them. They sound ready to bounce back.
I don't know if they'll land on line 3 with Kerfoot. But I'd bet Dubas and Keefe would be happy if they did. I think both will get a chance, if nothing else.
If they bounce back, it's a 3rd line I really like. If not, Vesey and Simmonds could both be waived. And I think we have the depth to bury them if they stink. None of us can know anything until training camp.
