Simple read.
Texans sent 85 in motion to find out whether the Pats were in man, match-man, or zone.
When Mills saw the end man 33 stayed wide to pick up 85, he knew the Pats weren't in pure man.
All he needed to do was to come off that read and moved his eyes to the next.
23, the guy who was originally on 85 had no business looking at the RB.
His job was to switch to the no. 3 reveiver from outside in, which was Auclair, the threat nearest to him.
The game was rigged to get the points to cover the Over.
