It's more like Jeanty RB1A, AK RB1B and Miller RB2. AK would be more of a change of pace, 3rd down, receiving option who probably stays on the field most of the time. Miller would be Jeanty's direct backup since their running styles are similar. As AK fades which he will fade, he always does, Jeanty can pick up more of that receiving role since he's a good receiving back as well. The Eagles were down to RB3 today b/c Barkley is banged up and Gainwell got his knee tweaked so they were down to Shipley to finish the game. Had it been closer, Barkley probably would've been in here, but teams have to have quality depth at RB.
