NFL Draft 2015: Pro Days happening this week

The Pro Day circuit continues this week with big-name programs like Alabama, UCLA, USC, Oregon and West Virginia hosting NFL scouts and coaches eying the top draft-eligible prospects.

The biggest prospects to watch this week are Trojans defensive lineman Leonard Williams and Ducks quarterback Marcus Mariota. Williams and Mariota are battling to be the first player selected after Tampa likely takes Jameis Winston with the first-overall pick.

Then there's a bunch of the top receivers in this year's draft working out this week, as Louisville's DeVante Parker, West Virginia's Kevin White and Alabama's Amari Cooper hit the field. All three pass-catchers will be on display this week, and all three figure to be drafted within the first 20 picks of this year's draft.

Oh, and we can't forget about Hobart offensive lineman Ali Marpet. The Division III phenom looks to continue to boost his stock as the draft inches closer, and after an eye-popping combine performance, a good showing at his Pro Day will further increase his chances of being drafted.
