I would say:
Tier I:
Malkin
Tier II:
Stastny (Wow, didn't know he had 65 points. Impressive. He's also a +6, while Malkin and Kopitar are both in the minus. He's very close to being a Tier I right now.)
Kopitar
Staal (It's hard putting Staal here as he only has 36 points, but his defense and shorthanded play is staggering. +15 tops all rookies. I'd say he's riding the cusp of Tier II and Tier III)
Tier III:
Vlasic (If he starts putting up more points I'd put him in Tier II, averaging nearly 22 minutes a game at 19 years old, and is a plus 5 on the Sharks, who barely ever score 5 on 5, is saying something)
Clowe (Yes, Clowe. Having done the math, had Clowe played the entire season he would have around 50 points while averaging less minutes on ice than Staal, Wolski, Malkin, Stastny, Pavelski and Zajac. Only Radulov plays less. If he played around 17 mins a game there's no telling what he could produce. Scary, I know, considering every Hockey video game has him rated as a 60 something. He'd also have around 93 PIM's)
Wolski
Tier IV:
Pavelski (Doing the math, he would have around 44 points in 68 games had he played them all. Plays pretty much the same amount of minutes Zajac does)
Radulov (Averaging about the same amount of PPG as Penner while playing less minutes and having a much better +/- at +11, second best among rookies)
Carle
It may come off as homerish what with 4 Sharks on there (though they're all in the lower Tiers), but looking at the stats and from what I've seen from watching, this is what I come up with.
