While that is true, there are a few things we can glean from the picture.
1) The RB appears to be moving parallel to the yardline and hashmarks. So we can conclude that the back is trying to bounce the run outside, toward the near sideline.
2) #41 (FB) and #88 (TE) have sealed their defenders to the inside. So we can assume (hopefully) that this was an outside running play with the FB leading the play.
3) #8 (Pos unknown, but will assume a WR) is blocking a defender back toward the original spot of the ball. If #8 is a WR, due to his positioning relative to the other offensive players on the field we can make a logical conclusion that the running play is a toss/sweep to the left of the offense and #8 is performing a crack block on the playside DE or OLB.
4) If it is a toss/sweep with the WR cracking down, #4 would likely be the CB coming up to try and make the tackle/force the run back inside. Due to his positioning, it would appear that the CB came too far upfield and the back was able to slide inside of the CB and avoid the tackle.
5) If all the logical conclusions from the still shot are true, then we can conclude that the blockers are in the correct position for the play and the RB was able to get to the edge of the defense.
