Yeah, the swing held him back from the power. I suppose most of us thought it was there to stay in that one MVP season, but it was an outlier.
Seems to me the contract complaints were from a small minority of fans, who just happened to be the loudest. Most fans were in favor of the deal or at minimum understood it was necessary. It would have never kept him out of the HOF, nor would it have damaged his reputation nationally, that was purely a midwestern passive-aggressive gripe every time he stepped to the plate.
But back to the swing though, perhaps my memory is foggy, but I seem to recall that the biggest complaint, which wasn't addressed in the article, was that for how respected he was as a bat swinger, he didn't adjust his swing to keep up with the changing game. He still tried to hit through the shift instead of hitting around or as most wanted, over it. As talented as he was, I think most fans figured he could have adjusted as well or better than other hitters who thrived during that time.
Either way, he's a HOFer.
