On Tuesday, UNLV lost defensive line coach Joe Seumalo, who helped the Rebels make the second-biggest improvement in run defense in the FBS last season.
On Friday, according to multiple reports, UNLV replaced Seumalo with Tony Samuel, who oversaw the nation's most-improved run defense last year at Georgia State.
In Samuel's only season at Georgia State, the Panthers allowed 181.1 rushing yards per game, an improvement of 122.3 ypg over 2014, when they gave up 303.4 ypg.
In Seumalo's only season at UNLV, which he left to accept the same position at Arizona State, the Rebels allowed 216.
