a 30 goal clip is just that, and nothing more.
some players have awesome starts to the season and score a dozen goals in the first 6 weeks, than dont break 20 in total.
TW is a consistent 20 goal scorer and usually averages 40+ points over his career (his career 'average' in goals/season is under 17)
He is a physical beast, and i would guess every team would/should be interested, and many would overpay, but, lets not pretend he's more than he is offensively, because nobody is trading for his offensive prowess
Mind you, if the Leafs got him, he'd get suspended for skating too close to a guy in the playoffs.
