Just a general self-serving statement that I don't make with enjoyment: I hope those "chicken littles" from this offseason like myself are now vindicated in the analysis of the 2018 team outlook. The glaring amount of busted draft picks, lack of young talent, and aging core roster has indeed caught up with this team this season, just as quite of a few of us pointed out despite angry posters telling us how wrong we were. It's not the end of the world, nor was that the prediction, as most reasonable people said this team would go from elite to very good, which has happened.
This thread is just one of a several: the front 7, the receiving core, just overall lack of young playmakers, it's all tied to the drafting. And maybe many can understand the frustration of trading a $120M quarterback for a mere second round draft pick, a 2017 starting quarterback for a bust wide receiver, and note that this team could have really, really used more draft assets and could have done better than a phone call to John Lynch (widely reported as the method how they "built a market" for Garoppolo, with many executives saying they didn't even know JG was available for trade at the 2017 deadline.)
All that said, things can change very quickly with the draft. It just takes 2-3 really good playmakers to change the whole outlook of the team. Clearly the front 7 would benefit most from an elite player.
This team still has the fourth highest odds to win the Super Bowl. You can still appreciate the greatness of this organization and acknowledge they've been one of the absolute worst drafting teams from 2015-present (while being one of the absolute best from 2009-14.) Take from that what you will.
