Record-setting Boston College tailback Andre Williams yesterday auditioned his talents before 29 NFL scouts gathered for school’s Pro Day under the bubble at Alumni Stadium.

Williams improved on some of his drills from last month’s NFL Scouting Combine in Indianapolis, where he ran a 4.56 in the 40-yard dash, finished in the top three among running backs in three drills — broad jump and the 20-yard and 60-yard shuttles — and finished with a grade of 5.6, which translates to “chance to become an NFL starter” in combine parlance.

“This is my first couple of months of real life so there are a lot of things to do and I’m really enjoying myself,” Williams said after his Pro Day drills. “Today, I was trying to improve on my 40 and just perform better at catching the ball, and I think I accomplished both of those goals.

“They told me I ran a better (40) than I did at the combine. Pro Day had its advantages because you on your home turf with your teammates so it was more a chill setting. At this, you see which (teams) are interested and who is in your corner.”

Williams, who graduated with a degree in education in December, has been living and training with family members in Marietta, Ga. He is a north-south power back with outside speed and is projected to go in the third or fourth rounds. Williams is one of handful of eligible running backs who played four college seasons.

The 5-foot-11, 230-pounder exploded into national prominence under the system devised by first-year BC coach Steve Addazio and offensive coordinator Ryan Day. Williams led the nation in rushing with an ACC-record 2,177 yards and 167.5 yards per game.

His single-season total is the fifth best in Division 1 NCAA history. He set the ACC single-game rushing record with 339 yards vs. North Carolina State at Alumni Stadium on Nov.  16. Williams was a first-team All-American, winner of the Doak Walker Award as the nation’s top running back and a Heisman Trophy finalist.

Williams, however, needs to improve his receiving and blitz-pickup skills if he wants to be more than a part-time performer in the NFL.

“I want to be a three-down back in an NFL offense,” Williams said. “I want to be able to do everything required from the running back position. . . . I want to be a diverse running back that can catch the ball and keep the chains moving on third down.”
