making moves

Look at TBs orgiizational philosophy Holloway isn't of interest. Robertson is always hurt and until he can put a couple of seasons of 70 gp the interest is minimal
TB also can pretty easily fit Colton in with a 22 man roster do some real gymnastics a 23. @2.975

Hollowell is likely never going to make it in the NHL.
Robertson is too much of an unknown for TB to make this trade. They can get more for Colton.

I think Holmberg's ceiling is 4c, Lafferty offers a better 3c option, but he is really not good enough in the long run.
Ekmann-Larsson is a gamble but not a bad one, I might do that.

If Colton is willing to sign for that he stays in Tampa. And if they are forced to trade him, that offer gets easily beaten.

I think a lot of the UFA signings are wishful thinking... teams will just extend those guys at those numbers.
