Interesting viewpoint. This sacrifice might help the QB realize his potential and make them more confident , so when chips ar edown, the QB can try to elevate thaie around him.
When we have a carousel of lousy talent, we pull the QB also down the quicksand. I think we shoukd try to maximize the next 3 years of Mac and go all in . And have the 4th year as reset year.
I agree that we need more help for Mac if he is going to emerge (like Tua seems to be doing, although we’ll see if he stays healthy).
I would argue the magic formula to build QB confidence is: a) organization/coaching, b) players and c) success/luck.
a) Compare the long time success with QB by someone like Reid or Shanahan (or Brady era Pats) to how orgs like the Jets or the Andrew Luck Colts destroyed many arguably very promising QBs.
b) is obvious and already discussed in this thread, Tua is latest example, once he got his WRs he suddenly looks amazing.
c) Success breeds confidence. Would Brady have reached the same heights if he hadn’t won a ring in Year 2? Or, Mahomes winning a ring so early? And there is always some luck involved with winning a ring.
