This has been an issue with Madden in the past as well. Would have defenders near the league lead in sacks or interceptions but they never showed up when looking at the league as a whole, but I could see them in my team stats. It's dumb and has been an issue for years. Not surprised it's carried over the this game as well.
It's also beyond ridiculous that you can win national awards and not be an All-American. I had a player when National Defensive Player of the Year and he wasn't even on one of the All-Conference teams.
