Was it not some solace that many of those terrible, game-defining WR mistakes were made by players who were destined to leave the team in short order? Pettis and Smith-Marsette can't cost us chances at a win, ESB is relegated to the bench and I wouldn't be shocked if he fails to make the final roster, and I think everyone would prefer that Poles cut bait with VJJ and give his roster spot to someone who has a better chance of success.
Small improvements across the board lead to large steps forward. Fields has a clear path to address his shortcomings, there is a committee of weapons that can handle an NFL defense, and while depth at OL is a concern, a few of the positions have competitive players. I really do think that this offense is one tackle and a center away from being genuinely good, with the only caveat being health.
