It's easy he hasn't achieved anything. He's been above average in any given season, but never better than #5, and only once.
He has great potential and can potentially become the best of the best. But it's just that potential, and it has yet to be realized.
He hasn't been that good this season. Amongst goalie who have played 10 games, he's 16th in S%, 9th in GAA (despite the fact we're 4th in SA). He's first in wins, but fairly sure he's not top 5 in win%.
