NFL draft prospects will be working out at the combine from Friday to Monday. ESPN Insiders Mel Kiper and Todd McShay answer 12 questions, predicting who will leave Indy rising up draft boards, how the under-the-radar players will fare and more.
1. Which prospect could run the fastest 40-yard dash?
Kiper: Keep an eye on USC's Adoree' Jackson. Speed is his best asset at the next level -- he can fly. He's an undersized cornerback (5-foot-11, 185 pounds) who isn't a true No. 1 corner, but his return skills add value.
McShay: Washington's John Ross recently clocked a 4.30 40 in training. That would be tied for the fourth-fastest 40 time among wide receivers since 2006. Florida State WR Kermit Whitfield also will be in the mix.
2. Who's the prospect who could jump into the top 10 with a great workout?
