The Rock/Booker T feud was secondary to the Austin/Angle feud that was going on in 2001. I'll say it again. Whenever Rock and Austin were in the company at the same time, Austin was always seen as the top guy even when he was a heel. The Rock always played second fiddle to the Rock and the only time Rock was the top guy was when Austin was out injured and I could debate HHH was right along up there with him.
This is somewhat true. In 1999 and obviously 1998, Steven Austin was far ahead of The Rock. In 2000, when Austin was injured, Rock was the top guy. When Austin came back, both were the top guys and it was very close, but I will go ahead and give the edge to Steve Austin.
In 2001, when Rock came back, again: very close as to who was the top guy, but I'm actually going to go with Rock here., Its debatable, and I could see how someone could choose Steve Austin for the last half of 2001. But in my opinion, Rock was the bigger priority.
2002: Both Steve Austin and The Rock were there, at the same time, for the first half of the year. There is no contest for this one: Rock was above Austin in 2002. Look at 'Mania 18. Who did they choose for Hogan? Rock or Austin? Rock was bigger in 2002. Steve Austin was feuding with Ric Flair, Big Show, and Scott Hall in the mid-card for most of his time in 2002.
Austin started as the bigger star. But by the time both men were nearing their retirement from pro wrestling (late 2001 - 2002/03ish), Rock had surpassed Steve Austin in the WWF's mind. That's my take.
And to answer the original question of this thread: Warrior was huge and I find him to be underrated, but there is just no way that he was a bigger draw than The Rock. No way. Rocky proved that he could draw and carry the WWF through its highest ratings even without Steve Austin (2000), where as I don't believe Warrior would have been able to do the same without Hogan. Keep in mind that, up to that point (and it may still stand today, not sure), Rock led the WWF to its most financially successful year EVER in 2000 (without "Stone Cold," mind you).
There are only two men who are bigger draws than The Rock. And that's Steve Austin, and Hulk Hogan. Other than those two, there is no debate. The Rock is number three, and by a wide margin. Those three stand far above all the others in terms of drawing power.
