2. Jaylon Jones, CB, Colts
The Cowboys traded up to draft cornerback Eric Scott Jr. in the sixth round and he's yet to play a game. Would they have taken two CBs in a row? Probably not, but for this exercise they absolutely should've picked Jaylon Jones in Vaughn's place.
The Colts selected Jones nine picks after Vaughn at No. 221 overall. Jones has taken his lumps like any first-year corner, but he's shown enough promise to start 10 games. He's allowed a 109.8 passer rating to opposing QBs, per PFF, but impressively has only allowed a 55.5% completion rate over 54 targets.
The Texas A&M product even packs a punch against the run, and is a sound tackler for a rookie. Jones has only missed two tackles all season and owns a 78.3 tackling grade. That grade is second on the Colts among defenders who've played at least 500 snaps.
The Cowboys aren't crying out for CB help, but Jones would give them another building block to develop behind Trevon Diggs and DaRon Bland, who are the only starters under contract for 2024.
