I'm going to have to jump in here.... While I do agree that borro consistently stuffs his foot in his mouth, as he has done here. You're taking this "Benefitted" from stars thing too far. For one thing, did you even watch any of those games? The stat sheet can say a lot, but it is just paper. While he did "help" from having good players on his team, those points aren't just handed out by the other players. I mean, he still has to be able to finish or setup the play for the others to assist. It's not like he just happened to be on the ice and got those points. And so Horton didn't play with talented linemates for the majority of his time, what's that saying? Is that saying he didn't have any chemistry with Jokinnen, or Valeri Bure, or Kozlov? Maybe the coach felt he wasn't "talented enough" to play with those players with some obvious offensive success. See where I'm going? I'm not suggesting that (because I don't think that's the case), but If anything, Horton not being on a line with those players is going to benefit (there's that word again) from not facing the top checking line or the top defensive pair, since they are going to go after the proven scorers. Like Semin did some of the year (read about 1/3rd to a 1/2), and like in my opinion Horton did most of the year (read about 3/4ths), until teams realized he was a decent threat in himself.
And your powerplay thing is a load as well. Did you even watch the Capitals powerplay at the end of the year? The whole powerplay was all Semin. All Semin, with a little Halpern running interference up front. He was creating, setting up, and running the whole thing. He probably should have had at least 10-15 more points if any of the players on his line had any finish whatsoever. See, Semin was looking for others to get things done by constantly making nice setups and passes, but his linemates did not have enough finish to do the job.
Oh, and on your note, Nylander was injured for most of last year, at least while he was there. Semin was on Jagr's line a total of maybe 3-4 games tops. Bondra played on his line a few times, but not a whole lot either. And yes, Gonchar was out there. But he wasn't exactly lighting the world on fire either.
Look, here's all I'm saying. Your opinion that Semin didn't earn all his points is garbage. Yes, he had a decent number of games where he played with some talented players. So did Horton if you want to make that claim. However, playing with talent does not mean the NHL automatically gives you a few goals here and there to pad your stats. You still have to earn the points.
The basis of this whole thread is stupid. It's apples and oranges. A power forward with a solid 2 way game, versus a flashy playmaking sniper. Both are talented, and both are going to be good. It's a pick your poison type of thing.
And borro generally puts his foot in his mouth. Just lay off him. Especially if you want to follow his own shoddy line of argument. It just makes you look bad as well.
