Robinson was excellent in limited action in Week 2, but it was Tyler Allgeier who got the first snaps of the game.
The Falcons are likely taking it easy with Bijan in anticipation of a large workload during the regular season, so his “split” with Allgeier this preseason shouldn’t be concerning unless we see it carry over into the regular season (which we won’t know until we get there).
Robinson did play 12 snaps to Allgeier’s 5, which is a perfectly promising share and enough that, if it were to carry into the regular season, Bijan Robinson could easily live up to his Round 1 ADP.
