Lee was named the Pac-12 Conference Offensive Player of the Year as a sophomore, when he caught a career-high 118 passes for 1,712 yards and 14 touchdowns.
Lee is a projected first-round draft pick.
As a junior last season, Lee's production fell to 57 catches for 791 yards and four touchdowns as he dealt with injuries.
He's a former Fred Biletnikoff winner. The award is given to the nation's top receiver.
Lee met with the Ravens at the NFL scouting combine in February.
At the NFL scouting combine, Lee had a 38-inch vertical leap, a 10-7 broad jump and ran the 40-yard dash in 4.52 seconds. He stood on those numbers at his Pro Day workout, but his top speed when 100 percent is in the 4.4 range.
"I liked talking with the Ravens," Lee said at the combine "That was a fun, good meeting. We'll see if they pick me in May, you never know."
