Nice article, thanks Superself!
I can definitely see the appeal of the seam routes. While the examples in the links are all successful plays, we definitely see Gase's route combos clearing the way for most of those plays. Also, there are a lot of errors by defenders and great decision making by Peyton. Those Jags clips though, just poor play all around, including Thomas. We have lacked that seam threat. This is what Gase wants and we're all hoping he gets in Thomas. Guys like Donta Hightower will not like seeing those seam routes.
Hopefully the decision tree looks like this: A) defenders tightly jamming the box with big heavy defenders, we audible to a seam route to Thomas, B) defenses plays out of the box with safeties defending those seam routes, we audible to Ajayi up the middle and battering ram them. Given Stills' speed on the outside, one safety will always have an eye on him. If Thomas is successful, and I expect that to be tested a lot early, this could help Ajayi to give us sustained drives between the 20's. But, for that to work we need to find 2 good run blocking guards who can get Ajayi a lane past the DL. Fingers crossed.
