I always hate the "X won a title (or more titles), so he is better" argument. It doesn't take into consideration who you had playing with you. Walker was not on very talented teams his JR & SR years. Yes, the 86 team was a contender, but only because Walker put them on his back. That's why Dale Brown played the Freak defense, to put all the focus on KW and have the other 4 beat them (which they didn't). Yes, Givens was "the guy" on the 78 team, but they also had Macy, Robey & Phillips. At most, the "title" argument is a tiebreaker.
But it is close between Givens and Walker. So, if anyone thinks Givens, I have no argument with that. I'll stick with Walker though.
