We've now hit the main attraction for the NFL Scouting Combine: the on-field workouts, and the defensive linemen and linebackers kicked things off at Lucas Oil Stadium while the tight ends and defensive backs addressed the media. Here are some of the highlights from Thursday's action.

-- The defensive linemen were the first group of players to begin their on-field workouts, and there weren't many burners during the 40-yard dash, but there were a few players who recorded a sub-five-second time. Leading the charge was Nebraska's Ty Robinson, who ran a 4.83 with a 1.7 10-yard split. Robinson (6-foot-6, 311 pounds) plays with a physical style and strong hands as a pass-rusher. NFL.com's Lance Zierlein views him as an eventual average starter, but perhaps his 40 time helped him move up teams' draft boards.

-- Commanders fans will love tight end Tyler Warren's connection to the team's history. When asked about why he chose to wear a No. 44 on his jersey, he shared a story about how his dad used to put on film of former Washington running back and Hall of Famer John Riggins and told him, "This is how I want you to run the football."

-- Travis Hunter's press conference was the biggest attraction on Thursday, as about one hundred reporters crowded around his podium. Most of the questions dealt with his versatility as a two-way player and what side of the ball he wanted to play on. Some teams like the Tennessee Titans, who hold the No. 1 overall pick, view him as a cornerback, while others see him as a wide receiver. Hunter said he would let whatever team drafts him decide, but if he had his choice, he would play both.

"Nobody has done it [in the NFL], but I feel like I've put my body through a lot," Hunter said. "I do a lot of treatment. People don't get to see that part, what I do for my body to make sure that I'm 100 percent each game. But I feel like I can do it because nobody has done it. I know I can do it. I did it at the college level, [where] we rarely get breaks. There's a lot more breaks in the NFL."

-- The cornerbacks will work out tomorrow, but Michigan's Will Johnson is clearly confident he'll have a good time for his 40-yard dash. Asked about people who question his speed, Johnson had one question: "Have you ever seen someone run away from me?"

-- Speaking of confidence, Kentucky cornerback Maxwell Hairston believes he is going to put on a show during his workout tomorrow and said people should "get your popcorn ready." He also wore a massive chain that said "Mad Max."

-- Colston Loveland, one of the top tight ends in this year's draft class, did his media availability with his right arm in a sling because of surgery on his shoulder. Loveland said he will be cleared for OTAs and ready for contact by training camp. Whenever he gets on the field, whoever drafts him will get a player who had nine touchdowns in his final two seasons. He feels like he's "one of the best route runners in the draft," and he'll have the chance to prove that to his new team in a few months.

-- Loveland isn't the only tight end who believes he's a strong route runner. LSU's Mason Taylor highlighted it as his most underrated skill.

"I think I run smooth, but...I can separate myself from defenders. It really depends on the route tree we had at LSU. We're kind of running basic routes, but I think I have the potential to run any route I'm asked to do ... I feel like I can run any route and be an answer for the offense."

-- Ohio State's Tyleik Williams and Arkansas' Eric Gregory showed good reaction and change of direction during the wave drills, which require prospects to move in whatever direction a coach points. Williams' movement was smooth and fluid as he moved down the line and had a good burst to finish the drill. Gregory wasn't as smooth but slightly quicker reacting to the directions given to him by the coach.

-- James Pearce Jr. has been known for being a freak athlete, and he showed that off once again by pacing the edge rushers in the 40-yard dash with a 4.47. Pearce is Mel Kiper Jr.'s sixth-best defensive end on his big board, is quick off the edge and knows how to create power with an undersized frame. He'll likely need to bulk up a bit at the NFL level, but he has the traits to be a talented pro.
