Good thing nobody who supported Sprong made that kind of compartmentalization a condition to his success.
I sure didn't.
Points are points. Sprong happens to be better at scoring them on the 2nd unit PP than some of our other complementary top 9 wingers (past or present) with less natural talent have been, which shouldn't be at all surprising. His shot from the left circle on the PP was probably his defining move in junior and in WBS, not unlike a number of high-end RH goal scorers in the NHL.
I mean sure, points are points. But he doesn't actually score more points than our other options, and he doesn't bring as much as they do outside of points. And when he has to be played with our skilled centers to be effective at 5v5, you really should be considering how he does at 5v5. Scoring on the powerplay is nice, but it doesn't make him a good top 9 wing option for us. He's simply not as good as Kessel, Horny, or Rust at 5v5. And we agree that he shouldn't be on our 4th line. So is he so good at the powerplay to be worth playing him on the 4th line anyway? Or so good that it's worth making a top 9 line worse to keep him in the line-up?
His ES numbers - 6 in 18 games - are just fine, particularly considering his most frequent center's been Henrique and not Crosby or Malkin like the guys he's being compared to.
His ES production per 60 with the Ducks is lower than Rust's short handed production per 60 over the last three years, which works out to very similar minutes. Even just this year Rust's SHP/60 with Cullen is very close to Sprong's ESP/60 with the Ducks. So sure, our other RWs are going to score a bit more at ES thanks to playing with Sid and Geno. But the fact that our other RWs can also be effective in other spots really is the key for me. It's a HUGE flaw that Sprong HAS to play with our top end players to be effective. His strengths simply don't justify that limitation considering our other options.
I'm not saying Sprong is a bad player. He's been solid to good every time I've seen him with the Ducks. But he's worse than our other options for the same positions except for on PP2. And since we simply don't have a decent position for him when healthy since he can't play on the 4th line, trading him made perfect sense to me. He's not so good on the powerplay to justify keeping him around just for the powerplay, or just to fill in when we have injuries.
