Lamar Jackson perplexed that other teams know their plays
The fact that he didn't realize that in a multi billion dollar business there's endless scouting information out there... Formations, down, distance, personnel packages, game situation, body language tendency, time in huddle, lip reading, signal stealing... Just wow. There's a finite about of information a player can learn so it's expected that many plays will be repeated. There's always going to be favorite routes, plays, etc.
This is one of the reasons Payton's offense is so successful. We run more formations and personnel groupings than anyone. We work hard to disguise our tendencies. Sounds like Lamar is either not a part of that game planning process or the Ravens do not value disguising tendencies.
