Modern pitching is going to have to be looked at different by HOF voters. We're at the point with hitting that numbers are starting to look normal again, so it shouldn't be an issue, but with the rules clubs are placing on their pitching staffs, there's got to be some give there. I would hope that isn't an issue, just a change in thought on what an elite pitcher's stats look like at the end of the career. Halladay, Sabathia, Pettite and Verlander are all HOF, I'd put Lee and Oswalt in there as well. That's 6 starters from one era which seems about right, but other than Verlander who will probably finish with stats that put him in easily all of the others are borderline which is why voters need to reassess pitching credentials especially when the new era of micromanaged pitchers see their day. Rivera is obviously in as well.
As for hitters ARod, Jeter, Pujols, Manny, Ichiro, Vlad, Chipper, Thome for those who are easily in already, MCab, Braun, Mauer and Cano for those who are on their way barring injury or complete drop off. With Chipper and Thome in, I can only think of one borderline guy and that's Helton and I'd say no. He was great for awhile, but he needed to do more in his 30's to have a shot and while he still hit for average, he didn't do much else.
