Clemson is hosting its Pro Day today, but it probably won’t do much to affect the draft stock of the team’s two biggest names. Sammy Watkins, Clemson’s star wide receiver, had a great college career and a great Combine and is a sure-thing high draft pick regardless of anything that happens at any workouts over the next two months. And the questions facing Tajh Boyd, Clemson’s starting quarterback for the last three years, aren’t really questions he can answer at a Pro Day. NFL Network’s Mike Mayock considers Watkins not just the best receiver in this year’s draft but one of the most complete wide receivers to come out of college in many years.
