With the spring evaluation period a thing of the past, Wilkinson is sitting on one scholarship offer, which he received from the Badgers in April.
"But Colorado State and Utah are on the verge of offering," Wilkinson said in a telephone interview Friday.
According to Wilkinson, the Rams and Utes told his prep coach, David White, that they were on the brink of presenting Wilkinson with his second and third scholarship offers.
What does Wilkinson like about his four primary suitors?
"Utah, their coaches are all cool, real down to earth and they finished in the top five last year," he said. "(They) have an excellent program.
"Wisconsin, they are just a defensive school and they are recruiting me for defense. Jeff Horton [UW's quarterbacks coach], he's a real cool coordinator. He's real down to earth.
"Colorado State: Coach Ballard [defensive tackles coach Karl Ballard], he's real cool… .I haven't got out there yet but I think we are supposed to be going to camp out there real soon this month.
"Cal, they have an excellent program and awesome academics."
Wilkinson went to one football camp last summer: at the University of Washington. This summer he hopes to attend a Colorado State camp June 24-26 and then make his way to Madison, Wis. for a Badger camp that runs June 26-28.
Wilkinson has taken part in three combines, beginning with a Scout.com event in January. Most recently, he participated in a Nike camp in Palo Alto, Calif.
"It went OK. My testing wasn't all that great but I ended up in the first group of DBs," he said. "I did real well for one-on-ones."
Wilkinson said he did nine repetitions on the bench press at 185 pounds, recorded a vertical jump of 33 inches, completed the short shuttle in 4.3 seconds and ran the 40-yard dash in an electronically timed 4.7 seconds.
In San Antonio in January, Wilkinson covered 40 yards in 4.68 seconds, had a 4.25 shuttle, 31 ½ vertical and a 6.94 3-cone drill. At the Scout.com mini-combine in May, he ran the 40 in 4.75, the 3-cone in 7.57 and the shuttle in 4.10.
