I'm actually on Heisman now with knockdowns at only 10 or 15 for them right now. I'm not a great passer so I need the help. My completion percentage is on the high side in the upper 60% range (not sure what it is right now) but I did play on AA for my first two dynasty seasons with knockdowns at 50. I think my completion percentage was in the 60s for both years but my TD/INT ratio was awful my first year. I think it was 13/14 my second year. Only played two games in my third year which is on Heisman but I'll know more over time.
I understand some players can play with high cpu awareness and knockdowns but I'm clearly not one of them. My sliders are for my skill level only.
