The Hawks have 4.6 mil to spend on Raanta, Smith and Morin. I don't expect them to keep Versteeg and his 2.2 mil salary, so if they can get someone to take him I.e. Buffalo, that gives us 6.8 mil.
I don't expect really the Hawks to make any big signing in FA since we don't have the salary space and it is going against the philosophy of building from within.
We have McNeill, Dandault and Teuvo who are potential centers of the future, and TT is the closest to being NHL ready, if not already. Don't see the Hawks trying to make any moves or signings that will hurt the cap space we currently have or need.
