I'm sure this will be a lively debate. With the talk of AJ Jenkins running the Hill with Jerry Rice, people are starting to say Jenkins is the next rice -- I know its hyperbole, but still.
However, it you really want to compare AJ Jenkins to someone, compare him to John Taylor. They're the same size at 6'0' - 6'1', 190 lbs or so, a lanky frame, quick acceleration, game-breaking ability, nice crossing route runner, and deep threat.
Judge for yourself.
