Yeah, I've heard people bring that up but different eras. You can't compare their numbers when Moose pitched through the heart of the "steroids era". Most writers seem to realize that and have admitted that he's probably a HOF from what I've read the last couple of weeks. 117 more wins than losses is hard to argue with, especially in the AL East.
Moose's era doesn't look as stellar as people already in the HOF but he compares quite nicely with his peers in his era. He finished in the top 10 of ERA 11 times in his career, only had one 20 win season but he had a bunch of 18 and 19 win seasons, including a season in the strike-shortened year where he probably would've gotten to 20.
