NFL.com has released its list Top 10 list of college football’s best running back duos for the 2015 season and Arkansas’ 1-2 punch of Jonathan Williams and Alex Collins has earned the No. 1 spot.

Williams, a senior bruiser, and Collins, a former five-star speedster, each rushed for over 1,000 yards last season and combined for 22 rushing touchdowns to help the Razorbacks finish with seven wins.

Collins has posted back-to-back 1,000-yard seasons as a collegian and is expected to be an early NFL Draft exit after this season. According to NFL Draft Scout, Williams is the third-best draft eligible ballcarrier for next season.

Here’s what NFL.com’s Bryan Fischer had to say about the dynamic duo:

The Hogs love to run the ball, so it should be no surprise that they have a pair of studs in the backfield. Both players rushed for more than 1,000 yards last season and could be better than ever in 2015. Collins, a junior, is looking to eclipse the 1,000-yard mark for the third consecutive season.

Other SEC tandems featured in the list include Georgia’s Nick Chubb and Keith Marshall (No. 4) and Alabama’s Derrick Henry and Kenyan Drake (No. 5).
