It's between Woods, McGrew, and Jenkins. All were first round picks who washed out quickly with minimal contribution. Reggie McGrew was pretty disappointing, but at least he stuck around for three years and played in some games.
Woods and Jenkins are remarkably similar. Both were receivers picked at the bottom of the first round (Jenkins #30, Woods #31) who were too soft to play in the NFL. They both left the 49ers in a "swap of first round busts" trade.
But Jenkins' complete lack of production is historic. Also, I can't think of another player for whom the door of opportunity was so wide open (great team, great coaches, redshirted his first year, spends offseason being tutored by the starting QB, #1 WR gets hurt, coaches spoon feed him chances in practice and in preseason).
Granted, the front office is different now than in Woods' time and Donahue probably would've kept Jenkins around for three years rather than admit a mistake. Still, Jenkins has no excuses, no mitigating circumstances, and absolutely no stats. Number one all time bust.
