The five-star Oxford (Ala.) talent is used to picking up offer from all over the country on a regular basis, but the Ducks' extension came sooner than he expected.
"I've been talking to them a lot, but they take some time to offer people," he explained on Friday. "They really want to get to know you."
After realizing the offer was his, Thomas admitted he was surprised.
"Coach [Gary] Campbell, the running back coach offered," he recalled. "I mean, I knew they had interest, but it was unexpected.
"He just said he wants me to visit and that he'll be here to see me in May."
"That's about the only school, well it is the only school our west I'm highly considering," he added.
As to why, the 5-foot-11, 194-pounder is a fan of Oregon's system.
"That spread!" he said. "And how they run the ball as well as how much they run it."
Thomas, who plans on taking the recruiting process "slow" from this point forward, is currently ranked the No. 3 running back in the class of 2014 on FOX Sports NEXT/Scout.com.
