There was an era where I felt a CB wasn't getting carries - seemed to deviate away from them but now I don't see that. My over-rides work.
USFL is a b*tch so I had a CB on decoy routes for speed and that funneled to interceptions. I had to yank him out of the route but that's my only experience in an over-ride backfiring to fail mode.
I think either a) my rule got missed in the shuffle - glitch or b) it was too aggressive and pushed boundaries leading to the sim engine to go nope...!! I placed it first now and caressed the parameters to what I know works. Upshot of the rule (since it really can't hurt me competitively) is if I'm up 29+ points - do this...
Play knowledge bomb the critical plays....why waste off useless runs.
