Can Berube get him to improve his game

To me, it's a question worth finding the answer to - but that's not to say it isn't extremely risky. Chucky has already gotten "fresh starts" with teams less structured/defensive than STL so there's not a huge chance that his all-around game improves with us... but, if he does improve, we're adding a nice shooting/PP threat PLUS freeing up 1.5 million against next year's cap. Every dollar is going to count next year, and IMO we will have a few solid, cheaper replacements for Sanford. On the other hand, if Galchenyuk doesn't improve, it would be hard to hide him in our lineup... maybe it could be a trial and trade before the TDL (similar to Tanner Pearson from LAK -> PIT -> VAN all in one season).

That's my thought. We know he has the ability to score but struggles in a defensive system. My thought is David Perron. He was a guy who always struggled in defensive systems but ever since Berube took over Perron has been arguably the most improved player. In my opinion, it's worth the gamble. Who knows, if it doesn't work then like you said, maybe the Blues could even flip him for someone else (like Kreider) and throw in another pick.

If the price is small, sure but I don't think any team can "fix" him.

Why do you think he is broken - is it effort/attitude, hockey sense, playing wing? Or some combo of those?

A little bit of all of the above? I fear he suffers from the same thing that Yakupov had but too a lesser extent. I thought maybe Yakupov was the bad apple and Galchenyuk wasn't but they were like two peas in a pod those two.

Tons of offensive skill, nothing between the ears.

Its ok when you are youngster and still learning but the minute you pass that age into full time "pro", you just look like an (___insert something funny to end my example here_____)
