It's been a loooong time since that was the case and I doubt anyone is basing their analysis off it. I totally forgot about it, frankly. Maybe at one point he projected as a good middle-six power forward, but that dissipated when he couldn't score consistently. I do remember Clifford-Handzus-Simmonds absolutely terrorizing the Sharks in 2011 when Kopitar was dead and Williams had one arm...but he never really took off after that. Which is fine.
But I raw disagree that he "sucks at everything else." But I guess maybe I have expectations commensurate with his role, I dunno. He scores at a 5-goal, 15-20 point pace per year, is near the league lead in hits, out-possesses his competition, isn't a defensive liability, is a good skater, good on the wall in possession, and is a model human being and teammate. He plays a very simple game, but don't confuse that with an ineffective game.
