Who? The only guy playing 3rd line minutes and scoring 20 goals is Brian Boyle. That being said, I find it hard to consider any guy who can score 20 goals a 3rd liner in this league.
Also, we're assuming that Korpikoski has hit his full potential. I'd wager against that personally. I think he has a few 25g/30a seasons in him. A guy that can put up those numbers, kill penalties, bust his ass every shift, and play all 3 positions up front? Those guys aren't exactly growing on trees.
Regardless, he never would have gotten the opportunity in NY that he has in Phoenix. Especially with Tortorella's "instant decision" mentality.
I mean Petr Prucha could score 20 goals in this league and he's a 3rd liner in the KHL. **** happens.
Let's pretend for a second that the trade of Lisin for Korpikoski (at the time) was a terrible move and we didn't make.
Now let's focus on the reality of Korpedo's career since leaving NY. The trade was made 2 years ago. Last season, for Phoenix, Korpikoski played 71 games, scored 5 goals, and added 6 assists for 11 points. Do you know where Korpikoski would've been this season if he had put up those points for the Rangers last year? Probably Europe, because I don't see what roster spot he would've won out this season (perhaps we don't sign Fedotenko if we have Korpikoski, but I think it's more likely that he would've simply been let go -- Fedotenko was coming off an abysmal year in Pittsburgh and still had 30 points to Korpedo's 11).
Kudos to Phoenix for having a lot of patience with Korpedo and getting a decent return, but even if we hadn't traded for him for Lisin, Korpedo is very unlikely to have been on the Rangers today.
EDIT: Of course, this is also ignoring the rumors that Korpikoski was unhappy with his 4th line role/fringer player on the Rangers and was threatening to return to Europe prior to the Lisin trade.
Stop it stop it stop it. This post has far too much perspective and rational thinking involved. BRING BACK KORPI. FIRE SATHER. CANT BELIEVE HE TRADED HIM FOR THAT PIECE OF GARBAGE LISIN!
