I'd have a hard time deciding between Taylor or Roy Williams at this point. Both players possess rare physical talent, and both possess tremendous upside at this early point in their careers. Williams may present a better need pick at this point-- given the dearth of big bodies in the Redskins' receiving corps, and the brilliant ability of Gregg Williams to compensate scheme-wise for talent gaps on his defense.
It ultimately comes down to which player would benefit the team more at this point, and I think Roy Williams probably would've helped the offense more than Taylor helps the defense. But I'm not complaining about having Taylor "Swoop"-ing around the field on defense, either!
