Looks like he's fit in perfectly with you guys so far. I'll be on the Rangers band wagon this playoffs, Not going to lie, I want that 1st round pick badly and think with the additions you made at the TD, puts you in a very good position to win a few rounds. Solid top 6 and bottom 6 depth, really good back end and the obvious vezna winner in net, not sure what else you can ask for.
Copp's opportunities in the top 6 in WPG always felt as he was a place holder and never seemed like it was a permanent position. Lowry isn't as versatile, so Copp was always his wingman on the 3rd line. Those two were always a reliable pair and complemented each other perfectly and were able to shut down other top lines so he was pretty much stapled there. He wanted more ice time, but our top 6 wingers were Ehlers, Wheeler, Laine (before the trade) and Conner at the time, and his lack of opportunity at C meant he wasn't trusted to fill that 2C hole and had to compete with Statsny (at both w and C) and Little (before his injury) and PLD after the trade,
He's seems to continue developing his scoring touch and now has back to back career seasons, proving he belongs in the top 6. He does go streaks were his offense isn't there, but has a solid defensive game to fall back on and contributes there. I felt he was always underrated and overshadowed by our big name players. I'm not sure how much more offense there is for him to develop, but at worst I think he's an elite 3rd line C and depending on his wingers, an area where you are definitely not lacking, could be a very good all around 200ft 2C - depending on where his offense caps out at and if he can remain consistent offensively.
I think it's likely he resigns with you in the offseason. Many Jets fans felt NY was his likely destination the past few years when he seemed to be positioning himself to get to UFA. The only other team I could see him being interested in is Detroit since he's from Michigan, however not sure how motivated he would be to go there after multiple playoff runs in WPG and hopefully a deep run with NY, unless Yzerman throws stupid money at him. Good luck Ranger fans. Props on the stellar quick rebuild.
