A good way to measure a player's importance is to track how his team performs without him. And by that measure, Ty Lawson is far and away the Nugs' main man. The Denver ballers have had a dispiriting season, but when Lawson is on the court doing what he does best — pushing the pace, passing the rock, and scoring buckets when everyone else has gone cold — they've been competitive, and sometimes better than that. And when he's been on the shelf with rib injuries and other issues? They could suck the cold off the North Pole. If any Nugget is indispensable, it's Ty.
