This is from Woj on Twitter:
I personally was skeptical to adding West because of his age combined with his knees, but for two years? Ten-million a year? I think this would be a straight coup. If he stays healthy throughout, by the time his contract runs out he'd be old enough to sign cheaply. If he gets hurt, it's not like he's on the books for a substantial amount of time. Win-win if this ends up happening. Exciting!
