On A mart I think he came along really well this past season and could make the team this coming year if he isn't dealt during the off season. He is a pretty fluid skater and while his decision making needed some work he wasn't too far off imo from being an NHL caliber dman.
He is kind of overlooked by allot of us due to Voynov Hickey Muzzin etc being in the fold but I think he is the most NHL ready of the group if we base things on last season.
As others have said, with the established youth on the kings already and the prospect depth I really don't see either of them breaking into the NHL with the Kings. They may need to look elsewhere to have a shot (like Moulson with the Islanders, though nobody expected him to score 30 goals on any team)
AHL player, max. Look at Piskula and Bagnall, that's what Kolomatis will be. Now Martinez on the other hand, has got a much higher ceiling, he made the team out of training camp but was then injured. Got called up once, didn't look sharp but that's his M.O., some plays you see flashes of brilliance and on other plays he doesn't look good
