Very true. Something went horribly wrong in Philly last year and I don't think anyone really knows what. Goedert is clearly an ascending player, while Ertz is either declining or at least plateaued. If I was the Eagles, I would try and get something for Ertz or shed his salary and use those resources to patch the rest of the holes on my roster (unless they think Hurts functions better in a 2 TE base).
For the Steelers...it is about 2 distinct paths. The "all in" with Ben where there is zero consideration to the roster beyond 2021. Everything is only about surrounding the aged gunslinger with as many supporting elements as possible to have one last ride. Cap ramifications, draft strategy, and long-term roster construction be damned. Honestly, if he is playing in 2021 -- why fart around and do anything else?
The other path is "lay the foundation" for a retooled and reloaded team. If this is the case, Ben should retire. No point in keeping him around. Find out what you have in Rudolph and Haskins. Get your other pieces in place and your new offensive system installed. If you need a QB, then get it in the next off-season as the final piece after you get a center, a guard, a young TE, and whatever else this off-season. Multiple trade-backs in the upcoming draft should be explored.
But knowing the personalities of all involved in the Steelers...they are going to try and do both of the above and likely accomplish neither.
