You're missing Lovejoy and Engelland in there, and then there's this Brain Strait (RFA), too, who I know nothing of. Plus, I think PIT wants to make room for another prospect D on top of Despres... Morrow, I think?
All that to say: PIT would have to make a lot of moves to fit Suter in.
Anyway, from an OTT perspective: how bad has Martin been? Like, has he just been underwhelming offensively (which doesn't surprise me)? OTT probably needs to add a steady lefty partner for Karlsson, to replace Kuba, and Martin could presumable be had for a half pint of Jim Beam and a pack of smokes. So, how bad has Martin been?
Looking over OTT's roster, you know what's really remarkable? OTT has zero bad contracts to get rid of. I mean, Spezza at $7 mil for 3 more years is an overpay of about $1 mil, but the term is reasonable, and Gonchar at $5.5 mil is an overpay for sure, but this is his last year. After that, the worst we have is.... Butler for $1 mil, for one more year. OTT's going to have a hard time effecting any dollar-for-dollar trades, if that's a priority.
For what it's worth, btw: Senschirp is tweeting today that $$ is not an issue when it comes to Nash (even if it was with respect to Z. Michalek):
"SensChirp @SensChirp
Hate to be a tease but I can confirm from a great source the #Sens interest in Rick Nash is very real and continues beyond Draft day. For what it's worth, budget has nothing to do with this. Melnyk is completely on board with any Nash deal."
