Barring setback, they (colts management) had been suggesting the earlier side of the timeline for Wentz and Q since the beginning. It was just a few on this board saying their friend's cousin couldn't walk 6 months after a foot surgery, so surely Wentz would miss half the season.
Side note, Taylor had been falling in adp with the Nelson, Kelly, and Wentz injuries. The return of these three have to be a relief to JT owners.
