The warning signs were there, from the moment Reuben Foster became one of the very rare draft prospects to be sent home from the Scouting Combine. After landing him at the bottom of round one, the 49ers boasted that they would have taken Foster with the third overall pick in the draft, if the Bears had selected Solomon Thomas in the wake of a San Fran/Chicago flip-flop of the second and third overall picks. Foster retained a high level of esteem among the 2017 draft prospects even after the 49ers explored all of the various red flags and rabbit holes of Foster’s character.
