I'd like to take as exemple Corey Potter from the Oilers. Potter played most of his pro career in AHL (321 Games played). Before that only around 9 games in NHL, then he's been called up by the Oilers and paired with Whitney and had a great season. Potter is 28 btw. I think Holzer is above Kostka, but if a dman is injured this season, Kostka will be the first call up. I don't see anyone taking a risk on Ranger early in the season if nobody is sure 100% about his shape. The guy clearly showed that he still can play, but can he last a full season? can he last on a regular job in NHL?
SIEGEL: KOSTKA A GENUINE LATE-BLOOMER FOR THE MARLIES
"I still feel like I'm getting better," he said. "It's funny, [I see] a lot of 21-year-olds on the [Marlies], I'll be 27 in November, but I'm in the best shape of my life, I feel like my game is still improving, there's always room for improvement."
