5. Indiana, Friday, April 1
Who to watch: As expected, offensive tackle Jason Spriggs tore up the Combine with a 4.94 second 40-yard dash, 31 reps on the bench and top marks among linemen in the broad jump and 20-yard shuttle. At 6-foot-6, 301 pounds, he can firmly place himself in the first-round conversation with a good pro day.
Also keep an eye on: RB Jordan Howard, DT Darius Latham, QB Nate Sudfeld
4. TCU, Thursday, March 31
Who to watch: Receiver Josh Doctson is an explosive leaper and showed terrific quickness and agility in drills at the Combine.
