It’s not that far fetched and is actually pretty sound.
When the Texans wanted to stop the run, they absolutely did. Four times on the last series actually. The touchdown was a missed tackle and as stated, everyone else was scattered. On the season the Texans typically allowed a bit over 3 yards per carry before Saturday.
I think they thought to take their chances with a less than 100% JT rather than risk letting Minshew hitting someone open for the big play. Slows the game down and makes it more predictable.
I know it’s the trendy thing to think Minshew is terrible but he did make some pretty great throws that game and has the capability to do so.
