The 6-foot-5, 230-pound Allar said he was "definitely excited" to add Tennessee to his growing list of college choices, which now features more than 20 schools in all.
"I talked to Coach Golesh and (quarterbacks) coach (

Halzle, and Coach Golesh was the one that offered me," said Allar, who's ranked by 247Sports as the No. 89 overall prospect and No. 6 pro-style quarterback in the 2022 class and the No. 5 junior from the state of Ohio.
"They said they really liked my ability to create something out of nothing and my ability to throw off platform. They also really liked my arm strength and sense of the game."
Allar said he was happy to find out about the offer, "and I’m looking forward to talking to the staff more and learning more about Tennessee."
Heupel was hired Jan. 27 to replace former Vols coach
Jeremy Pruitt, who was fired Jan. 18 amid an investigation into alleged NCAA recruiting violations. Allar said he's eager to find out more about Tennessee's plans under Heupel and his possible opportunity with the Vols.
"Well, I know that it is a completely new coaching staff," Allar said, "so I’m looking forward to getting to know them better."
With the ongoing dead period for recruiting having been extended through May 31, he said he's looking into the possibility of traveling to some schools to see them on his own before the end of the dead period as he continues to work toward his college decision.
"Right now, I'm still talking with my family to see if we're going to go on any self-guided tours, but I'm definitely going to try to schedule some virtual visits with different schools," Allar told 247Sports' Tom Loy this week.
"As far as the dead period, hopefully they don't keep pushing it back, because I definitely want to like take some official visits because that's going to help a lot, too. But if they do keep pushing it back, I'll definitely try to get out and see some of these schools on my own. That's really where I'm at with that."
