Lupul definitely has more skill. I think you expect him to be a 25 goal scorer, with Clowe he seems more like some thuggish tough guy who you are fine with like 15, I wouldn't expect him to put up the numbers he did last year every year and even then. But God, does this board love intangibles, or what?
I would take Clowe though personally with the contract situations being what they are, but simply choosing the best player? I would expect these results maybe if you put him against Michalek or something.
