Cole may have had some recent struggles, but his track record suggests he's a much much better player than Pateryn. Cole had 26 points in 65 games last season and has multiple seasons with 20-25+ points. Pateryn's career high is 13 points and he generally struggles to even reach double digits. Much different caliber of players offensively.
When you look at possession numbers Cole is much better than Pateryn as well. Pateryn is a minus in terms of possession and is also even a minus in relative possession numbers compared to teammates. Blocked shots, hits, takeaways, etc Cole blows Pateryn out of the water.
His statistical profile actually looks a lot like Brodin's (though obviously Brodin is better). With Pateryn, you're hoping that he doesn't hurt you when he's on the ice. Cole can actually be a difference maker, let alone not hurt you.
I'm not sure why people are mad about this trade at all, the cap space difference is not going to be the difference between making a move or not making a move. The Wild's 3rd pairing gets markedly better and the Wild can effectively expect offensive production from all 3 d-lines now. Given the Wild's center situation and lack of scoring ability from their forwards outside of Fiala/Kaprizov and maybe Parise... the Wild need offensive production from their D and this helps them do that in a significant way.
I'm not sure how many of you have actually played hockey, but there's plenty of players that actually prefer playing on their off-side--it's actually easier offensively. Really the only downside is you're having to catch passes on your backhand more often, but it's really less of an issue as long as you're not a wing.
I haven't particularly liked a lot of Guerin's moves and the value that we've gotten in return, but this is a really underrated move.
