There ought to be an all-time schmucks section of the hall with guys like Cap Anson, Landis, Rose, and several others in it. We can argue about Cobb.
More seriously, Rose's longevity probably should be seen as a plus. He's the all time leader in hits and games played. Did he stick around a few years too long? Maybe, but to end up with an average over .300 in his era should be seen as a plus. In my mind, displaying my Boston bias, I look at Rose like Yaz, who also was mostly an accumulator and longevity guy with some great seasons in his prime.
