This is definitely going to turn out to be a poll thing as this is a coin-flip if I have ever seen one. So, without explanation, I am going to go with Tim Brown... well, I suppose for "'name'sake"!
Taylor's had a td catch in three straight. Tenesee is right on the edge of being a bottom ten team against the recieving game. Granted, Arizona IS a bottom 5 def against the recieving game, so Brown's not a bad play, but why going lookin' to catch the hot hand when you've already got a hot hand goin'?
I think that Taylor should have more opportunities to touch the ball than Brown will. Brown has to fight for touches with Garner, Rice, and now Porter. Taylor only has Lewis, and Heap to a lesser extent.
