Given that he only played one year and Russ played 4, I don't see how it's a fair comparison at all.
In fact, I don't see how anything can be there "on paper" because Kyler never worked out for us to have any numbers on paper. But hey, you're saying he needs to show it on the field, so fine by me, I guess.
Most of the comments don't come with any caveat, just that he's the greatest thing ever and will transcend the game, and all historical evidence against him.
Edit: I guess I just can't get behind the "on paper" argument. On paper, coming out of college, you could argue that Matt Leinart was better than Tom Brady, but that's clearly not true. You can bend those stats however you want, so before I even slightly imply they might play on the same level, I'm parsing my words.
