They should have kept Pickett, hired a competent OC, added better WRs and fixed the oline. There's isn't a coherent reason to add an old, washed up bum like RW to an overall roster this bad. Based on how they handled Pickett, they have no clue if the could win big with him or not. But we know the floor was likely going to be in the 10-7 range with him at QB this season. They should have known RW and/or JF wasn't moving the needle for this team. It was silly to think otherwise.
The long term solution was to trade TJ and Minkah 2 or 3 or 4 years ago for picks and package those picks for a top QB. Now, they missed that window for peak value.
The stillers are in NFL purgatory due to their awful assessments and developments of players. Here's how bad it's been, the 2017 first round pick was last first round pick to have their 5 year option picked up. The next first rounder who could be picked up is Jones, there isn't any guarantee that he will be worth that option.
