As we all know, Greene has emerged as a solid two-way defenseman. We have also seen guys like Corrente, Fraser, and Eckford get some NHL time with reasonable success.
Maybe I'm a super skeptic, but I'm just not sold on Greene totally yet. Defensively he scares me a bit and has absolutely no strength. Before I let Paul Martin go, I want to see Greene in March/April.
People keep forgetting this guy hasn't played a full season of hockey for 2-3 years. He may just hit the wall like Oduya did his rookie year. Greene's been playing very well offensively and decent enough defensively - is he a #1 guy? No way.
Fraser is tolerable, Corrente isn't ready and Eckford forget it.
Paul Martin is hands down the best defender on the team and should be resigned - within reason, that is.
