I think he was a good player, and if he had stayed healthy earlier in his career, would have been an great player, bordering on elite.
However, he was barely a 1st line center, a good 2nd line center and a great 3rd line center. He scored more than 70 points once in his career, more than 60 points twice, and his career high for goals in a season is matched by Kyle Brodziak. He had a small chunk of time between 2008-2011 where he looked like he was breaking out as a first line center, but could never seem to get over that hump.
Don't discount (for now) that he also played his entire career in Minnesota, which is no small feat (especially over 1,000 games).
