Weights on hockey websites are notoriously unreliable because there's never any evidence that they're updated. That said, I do think people overestimate preseason results - Smith did look excellent there, but he's going up against AHLers and NHL veterans playing at 75% speed. Furthermore, he didn't have to beat out roster players, he had to beat out the starters, and that just wasn't likely to happen - Mueller would've had to look awfully bad for them to throw him aside and start Smith over him. He'll be here next year and hopefully even more prepared.
