He's still young enough that he's got another 3 or 4 years of high level play left in him. He'll break 1000 probably by the end of next season, and I'd say 1200 is in reach.
He'll likely finish his career in the top 50 in NHL history for points, combined with very good defensive play and with a cup to his name, I think he's on a HOF trajectory. The highest scorers eligible for the hall who aren't in are Roenick and Nicholls at a shade over 1200 each. Though you wonder if his dirty reputation would be held against him if he's a borderline case. Roenick is probably being held out because of his personality, but he was more one-dimensional as a player than Brad. I think he's solidly in the hall if he finishes in the 1200-1250 range.
