I’ll expand. Bills player Johnson said after the game that tape showed Jackson doing the same thing a lot. So he baited Jackson expecting him to do the thing he saw on tape.
The problem with RPOs and that type of offense is that a lot of the passes are one read only. When they fake the run to pass it’s usually a slant throw to a WR or a seam pass to a TE after the LBs suck up for the run. What Jackson would need to get better at is if that first read is no good then to see what else develops before taking off running.
Some of Jackson’s struggles does have to do with lack of good WRs and TEs that were hurt a lot. Need weapons to throw. It’s not all Jackson but I see some similarities to RG3 who didn’t do well standing in the pocket and reading things. Some routes take more than 3 sec to run. Can’t have a scrambly, want to run 50% of the time QB instead of letting corner routes or crossers not develop.
Maybe Roman is part of it too.
