Gone for so long and the conversations have hardly changed at all.
Cholowski's demotion last year, much like the year before, was likely to allow him to develop against a more appropriate level of competition. He wasn't effective in the NHL; playing in the AHL was better for him. Considering he really didn't improve at all from his first year to his second, and now hasn't played in 10 months, I wouldn't expect much this year. Maybe he'll surprise, but I won't hold my breath.
He has not been good offensively. 24 points in 88 games. Not even that good in the AHL. 25 points in 55 games. Dekeyser level offense .69 P/60 last year with 2:40/g PP time. For comparison, Daley (who you call one of the worst in the league) with less than a minute PP time per game scored .63 P/60. Staal and Stecher both produced better without any PP time worth mentioning. At even strength, Nemeth, Biega and Merrill all produced more.
You made the same arguments about Smith and Sproul. Like once you label a player an offensive defenseman you'll say he's "good offensively" no matter how he performs. If he was actually good, he wouldn't have any problem beating out the likes of Daley or Biega or Merrill. That's why Hronek has stuck despite his own somewhat weak defense.
You like to say "be given every opportunity", but what you really mean is that he should be given a spot no matter what. You know there's nothing Staal, Merrill, Biega, or Lindstrom (or likely even Nemeth, Stecher, or Dekeyser) could do that would make you believe they deserve a spot over Cholowski. And you're against adding anyone you think could beat him out, like Vatanen. We can gift him a spot next year, no need to do so now when he's still waiver exempt.
Granted, Vatanen isn't good enough to make a big deal about, but I do think we should make every reasonable effort to improve as much as we can. I personally think a major factor in last year being such an embarrassment was Yzerman writing-off the season before it started, and he's done essentially the same thing this year. Getting too used to losing, or even worse wanting to lose for a higher pick like most fans seem to want, is terrible for a franchise.
