ESPN: Best Pac-12 positional tandems of 2017 at Washington, Colorado, USC

Sometimes a position has one generational talent, but ideally in college football, you have a duo that can create all sorts of problems and mismatches for an opposition.

According to ESPN, there appear to be three such duos that will cause all sorts of trouble for college football teams this season.

Husky backfield: The Washington Huskies have been lauded for their defensive talent. But the duo to watch this week is on the offensive side of the football, where they have the running game and the offensive line that can complement their monster defense.

Myles Gaskin and Lavon Coleman, Washington: A true thunder-and-lightning duo, with the smaller Gaskin rushing for 62 percent of their combined 2,225 yards last season -- the No. 2 returning total nationally behind Western Michigan's Jamauri Bogan and Jarvion Franklin.

Buffs wideouts: The Colorado Buffaloes appear to be replacing a lot of talent in a lot of places, but one spot where they have a good duo to rely on: Wide receiver! If they find the right quarterback.

Devin Ross and Shay Fields, Colorado: Life without Sefo Liufau could hurt the productivity of this senior duo, but their talent is beyond question after Ross earned first-team All-Pac-12 honors, and Fields actually outgained him with 883 receiving yards in 2016.

Trojans defensive backs: The USC Trojans are loaded with talent everywhere. But the place to really watch where USC takes that step back into the national spotlight is in their secondary.

Iman Marshall and Jack Jones, USC: Another high-talent combo, led by a veteran in Marshall, the former No. 1 corner prospect nationally who thrived last year opposite Adoree' Jackson. Jones emerged last year as a freshman and enters preseason camp with the inside track to start.
