Fields and his dislocated thumb

What frustrates me the most about the chronic failures of the Bears franchise regarding building a good offense - is that they have not done the most basic things needed for success on offense.  It begins with the offensive line but obviously doesn't end there.  

It is not that difficult to build a solid offensive line.  Certainly it is easier to do than to draft a great franchise QB.  Right?  Interior OL are not difficult to find in the draft or FA.  Tackles are harder, but still not THAT tough to find.  You may whiff on a tackle but just go right back and try again if you do.  And you probably are not going to build anything special with late round draft picks.  You have to invest high-level resources (draft or FA) in your tackles.  But again, that is so doable.  Bears have not built the OL.  That frustrates me.

The skill positions are not that difficult to find also.  Not easy, but it's not like finding unicorns.  But yes, you do need to invest top-level draft/FA resources if you expect to get top-level skill talent on offense.  The Bears have invested some high level draft picks, but they need to do more if they expect more of a ROI with these players.  D.J. Moore is a nice addition.  Kmet is a good TE.  But the team needs more than those two - and the WR & OL unit should have been built before Fields was even drafted.  Before.  People can argue that point, but I'm just saying don't expect the O woes to go away without better WR and OL talent in place - just "drafting another kid" at QB won't solve our problems if the infrastructure is not there on offense to maximize the odds of the young kid succeeding.  

There is nothing "new" to this.  It (to me anyway) is NFL 101 stuff.  Invest in top level talent on offense if you expect top level results on offense.  If you whiff on a WR or OL, don't give up... pony up another pick and keep trying, until you get it done.  If the GM is incapable of getting it done, then yes, you need to replace him.
