With Purdue coaches surrounding and a possible scholarship offer at the end of his 40-yard dash, Tranquill was clocked at a personal-best 4.49 time.
"It felt great," Tranquill said Tuesday's camp. "Obviously, this camp season takes a toll on your body. I just tried to battle through it and I was blessed to run a 4:49 today."
Tranquill, a 6-foot-2, 200-pound prospect, was set to attend Purdue's Elite Camp for seniors on Friday but was a late scratch. Instead, he worked out for the coaching staff on the side of their underclassmen camp.
Purdue linebackers coach Marcus Freeman worked with Tranquill on several drills, getting an up-close look at his athleticism.
"It was obviously a great opportunity," said Tranquill. "... It was great to give me a different perspective—for my game, and to be recruited. I was thankful for that."
Tranquill has been on the Boilermakers' recruiting radar for some time. Purdue is recruiting several linebackers, with recent visitor Noah Furbush at the top of the list. Tranquill may have forced head coach Darrell Hazell's hand with his impressive performance on Tuesday.
"I've been getting a good vibes, obviously," Tranquill said. "There are some new offers out, but Coach Hazell is being really particular about who they offer. At the end of the day, Coach Hazell was beyond impressed. They're going to meet Saturday and again on Monday, and hopefully call me with some good news next week."
Tranquill is hopeful he has momentum built during these summer visits. An offer from the Boilermakers would be icing on the cake.
"It would be huge, because they're one of my top schools—or I wouldn't be visiting them," he said of Purdue. "They've got a great program and what I'm looking to study. It's a blessing anytime you get a scholarship and get a chance to go to school for free. It would be huge for me."
