The difference you and many here imply is just not there. They succeed in very different situations. Situations I assume ARod understands much better than you, I or anyone else on CB. I assume ARod uses the differences to maximize effectiveness for both. 5.5 and 5.6 YPC are great averages. Clearly ARod is getting great results with both. Maybe they should be used more? Probably would have been better than some of the Red Zone performance recently...
