I always liked Boggs, and especially Gwynn, as players, but it would certainly be fair to call them fairly one-dimensional. Gwynn had a lot of speed, and in some ways, it's hard to believe he wasn't more of an offensive force. You point out his main shortcoming, which is very low walk rates. I don't know to what degree this is true, but it would almost seem that he swung at some pithes out of the strike zone and turned them into hits, whereas other players may have drawn walks. A hit is certainly better than a walk since it can advance baserunners that are not forced (such as a runner on second), and can sometimes advance runners more than one base. But Gwynn had a just a 50-point difference between his career OBP and career BA (.388 vs .338). Boggs had a much bigger difference of 87 points (.415 vs .328), and Raines did too (91 points, .425 vs .294.)

Personally, I think Raines compares favorably with Gwynn, and roughly equal to Boggs. But the latter two guys were swept into the HOF quickly and I don't think Raines will be. I hope he makes it within a few years.

That is, for every time Tony Gwynn came to bat, there was a .489 likelihood that he would advance a base. Usually, he made an out; sometimes, he hit a double and stole third; but on average, he moved the Padres .489 of a base toward a run. Raines’s contribution was 12% greater, .547. One can argue that Tim Raines was, over 20 years, a measurably more potent offensive force for his teams.
