The arguments on this board about not giving Fields weapons is quite fallacious.
Every single previous GM in recent Bears history has tried building around the quarterback and it has failed. We gave Cutler Marshall/Jeffery/Bennett and Mike Martz and that didn't work. Why? The QB wasn't good. We did the same with Trubisky with Arob/Graham/Mooney, and it didn't work because the QB was bad. Angelo, Emery, Pace were all fired because they kept spending on FA and reaching in drafts to supply a QB and help make the QB look better. This formula doesn't work.
Teams that had good QB's didn't always have great offensive lines and receivers when they won super bowls. Just look at Russel Wilson, Tom Brady (won a SB with Branch and Givens) and Aaron Rodgers (35 year old Driver and Greg Jennings, and a TE no one remembers). At some point in time these QB's showed how great they were, even when they didn't have surrounding talent.
If we draft for weapons around Fields, and he isn't a good QB, then we will have a bad defense and a bad offense. Whereas if you draft best player available, you start to build a complete team that can be loaded with all-pros who win regardless of bad or average QB play (Lovies Bears era as an example, winning with Grosmman and Cutler). If Fields is a legit QB, he is going to make the receivers around him look better.
That being said, last year Fields had a horrible situation where he had bad coaching. So there isn't really any indication on what he is yet, therefore building around a player who may not be here after his rookie deal, is setting us up for another rebuild. It was unfortunate the Nagy didn't do this as it would have allowed the Bears to do what Cincy did for Burrow, but we aren't there yet. Fields needs to prove that he is worthy to invest in, and he hasn't done that yet.
