Flexbone – Wear and Tear

Running a test dynasty with Air Force, my experience with Wear and Tear (WnT).   I’ve played 4 games and I’m a little worried.  Default settings, on All-American, 6 min qtrs, on PS5.

Year 1. BYU (81ovr) at AF (71ovr). Rain. Loss 14-20. 
Lost FB Carson on 1st play. Then HB Harris broke collarbone on 3rd play.  QB didn’t make it to half.  Multiple injuries on OL. Was basically running 2nd team offense at end of the game.
Year 2. AF (61ovr) at Utah (82ovr). Clear. Win 24-14. 
No injuries this game. But lost starting HB and FB to WnT.  QB was unable to finish the game.
Year 3.  Cal (71ovr) at AF (63ovr). Rain.  Loss 3-6. 
Lost best HB on 1st play. QB on 3rd play.  We ended up losing 5 HBs to WnT.  I ended up with 9 guys with carries.  Couldn’t keep the players on the field.
Year 3. AF (63ovr) at C.Car (61ovr). Rain. Win 38-21. 
Again, QB didn’t make it to half. Lost top HB and FB.  2nd HB was in and out until late in the 4th when he got knocked out. 

I’m running a realistic flexbone offense, passing more than the academies do in real life.  40-20 run/pass plays per game.   Getting between 300-400 total yards, except in that Cal game I only had 130.  
Is it the rain (3/4 games)?  Is it playing better teams?   Or can you not run the flexbone in CFB 26 on default settings?   I see they gave Army, Navy and AF QBs Workhorse.  If it is required, you have to get lucky in dynasty to get more QBs like that. I’m using “pure runner” QBs.  None of the HBs or FBs got more than 10 touches a game.  Everyone gets hurt or becomes unplayable.

If WnT is optimized for CUT and Road to CFP, can we get better defaulted sliders in Dynasty mode?
