It was another day of evaluation in Indianapolis. The defensive backs and tight ends were next up at the podium, but the on-field workouts, which generate the most excitement, officially kicked off with the defensive linemen and linebackers going through drills. Here are some of the highlights from Thursday.

-- The defensive tackles were the first group up for the 40-yard dash, and there were several who had sub-five second times. Penn State's Zane Durant, who recorded 25 tackles with four sacks, paced the first heat with a 4.76. Durant put up strong testing numbers overall, finishing in the top five in the vertical jump (33.5 inches) and broad jump (9-foot-4).

-- After days of speculation, we finally received confirmation on Rueben Bain's arm length. It came in at 30 7/8 inches, which is not the shortest length for his position but is third-shortest among defensive tackles. Bain is considered one of the top pass rushers in this year's draft class and could be a top 10 pick. There were several questions from media members about his arm length, but Bain said that teams haven't been as concerned, choosing instead to judge him on the numbers he put up at Miami.

-- The defensive tackle group obviously contained some of the biggest athletes in the draft, but many of those players showed they have plenty of explosiveness and power. Caleb Banks, who weighed in at 327 pounds, recorded a 32-inch vertical, which ranked seventh for his position. Clemson defensive tackle DeMonte Capehart had the third-best vertical for the position at 33.5 while weighing 315.

-- It shouldn't come as a surprise that there was a large crowd surrounding Caleb Downs, who some consider to be the best player in this year's draft. Downs, who is a popular projected pick for the Commanders, said his confidence level is at its highest when he's on the field because of how he can break down the game. Downs has been praised for his versatility, as he can play both deep safety and closer to the line of scrimmage.

-- One more thing on Downs: while he is considered a top-tier talent, there are questions about whether the position he plays will push his value down. There have only been three safeties taken with a pick higher than seventh since 2000: Eric Berry, Sean Taylor and Jamal Adams. Downs dismissed those concerns, saying "at the end of the day, it's 'Who's the best defender?' It's not about positional value. It's about who affects the game."

-- LSU cornerback Mansoor Delane broke down the differences between playing in the slot and on the perimeter. "There's a lot of grass," he said when describing the slot, adding that quicker receivers and tight ends usually thrive in that area of the field. However, Delane is confident that he can play well on the inside and outside in any scheme or role.

-- David Bailey made the unusual decision for a potential top 5 pick and decided to participate in drills in Indianapolis. The Texas Tech product did not disappoint; he ran a 4.51 on his first attempt at the 40-yard dash and ranked third among defensive ends in the broad jump. Bailey could be shooting to be the No. 2 overall pick, and his performance on the field certainly helped make that a reality.

-- Ten-yard splits carry more significance for players near the line of scrimmage, and while Bailey was certainly the fastest in the 40-yard dash, he was actually sixth in 10-yard splits. Malachi Lawrence -- another projected first-round pick -- paced the defensive ends with a 1.58, and Texas A&M EDGE rusher Cashius Howell came in second with a 1.59.

-- Although Bailey was the star of the night in drills, Penn State EDGE Dani Dennis-Sutton put together a strong showing and tested near the top in the 40, broad jump and vertical. He ran a 4.63, which ranked fifth among defensive ends; he had the fourth-best vertical at 39.5 inches; and he led the position with a 10-foot-11 broad jump. NFL.com's Lance Zierlein currently has him as a good backup who could develop into a starter, but he could rise up draft boards by the end of the week.
