A good post. Yeah Chiarelli said something like they wanted Puljujarvi to concentrate on his defensive game as he's not worried about the offense, but I couldn't find the quote right now. Fleming also said the following:
Jesse’s offensive abilities are always going to be there. He sees the ice extremely well and has great puck skills. He’s got more chances, but they just haven’t gone in. It’s his play away from the puck that we’re really trying to emphasize here, straight lines, stops and starts, finishing (his) checks, defensive zone positioning and awareness away from the puck.
While I understand some of the things Fleming said I think a different kind of emphasize would've been better. As for Jesse's AHL career it'd been interesting to see how his production would've been if he'd stayed there longer as he scored 4 points in his 5 last games and clearly started to get it going.
Also IMO the first season wasn't that bad considering the age of 18. These are from Chiarelli at that time:
"He's going to be in the conversation come the deadline," said Chiarelli. "He's a dangerous player down there. He was far and above the most dangerous player I saw in both the games down there."
“I’m happy with his development, Chiarelli said. “He’s going to be an impact player. Every time he touches the puck in the American League, it pretty much turns into a scoring chance.”
