Definitely the most consistent.
He wasn't the best every single year, but the guys that were usually better than him in any given year (minus maybe Roy and Hasek during his time), were not better than him every year.
And I still think his best season was 07-08 when he was 35.
He fell off a little bit at the turn of the decade, but that was pretty understandable. 38 years old, a zillion miles on the odometer, season after season of 70+ games played.
One thing I was dead wrong on was that back in the early 00's, I remember saying that he'd probably be retired by 2010 at the latest. I never saw him playing into his 40's, until he was in his mid-30's or so. Maybe when he signed that deal that had him under contract until 2012, I thought ''Alright, looks like he will play until 40''. I saw Roy retire at 37 and figured that Marty would probably retire at the same age, but also knew that he'd break the wins and shutout record, just not as extended as they were. I remember being on Marty record watch by the early 2000's. I figured he'd break the wins record in 07-08, barring long term injury and the shutouts record by the last season of his career, which I assumed to be 2010 at that time. He broke it in December of 2009. I also didn't think we'd lose a whole season to lockout when I started to think about it. He would have broken the wins record in 07-08, but lost all of 04-05 to the lockout.
