Isaiah Gilchrist landed an offer from Washington when Steve Sarkisian was the coach there but he was still surprised when USC offered him on Monday night.
The four-star cornerback from Bellevue, Wash., said he knew the Trojans' coaching staff was interested in him but he was taken aback by getting offered so soon.
"I knew they were probably considering it since they offered me earlier when they were at Washington but I was not expecting to get offered," Gilchrist said.
"They have been sending me camp information. They were showing some love but I just wasn't expecting to get offered."
USC joins Washington and Washington State on the offer list for Gilchrist, a 5-foot-11, 180-pound four-star prospect who's rated No. 15 at cornerback and No. 231 overall in the 2016 class by Rivals.com.
Since Sarkisian used to coach at Washington, Gilchrist said he's pretty familiar with him and the other USC coaches and that could play a big factor as his recruitment moves forward. USC also offered 2016 teammate Isaac Garcia, a four-star defensive end, on Monday.
Landing an offer from the Trojans definitely carries a lot of weight for the four-star recruit.
"I was around them a pretty good amount," Gilchrist said of the new USC coaches. "It wasn't like I was there all the time but I know them pretty well.
"It's a big thing. It's a very big school. Everybody knows about USC football. It's big for me."
Gilchrist has the three Pac-12 offers and he said basically every other Pac-12 school has been showing steady interest. USC is recruiting him as an athlete while Washington and Washington State like him strictly at cornerback.
