Nevada is being particularly hard-hit right now.Over the weekend, the Wolf Pack lost starting wide receiver McLane Mannix and starting safety Nephi Sewell to transfer. Mannix, a sophomore, was a freshman All-American in 2017.Citing “personal family reasons,” Mannix announces his transfer on Twitter on Sunday.“This has not been an easy decision for me,” he wrote. “I have made lifelong friends and learned many lessons both of which, I will always be grateful.”Thank you for the memories #JungleBoys pic.twitter.com/DOypQnhFhc— McLane Mannix (@mclane28) December 3, 2018This season, Mannix totaled 50 receptions for 875 yards and seven touchdowns.
