From Grier's perspective, he'd relish the opportunity to come to the Patriots even if it meant sitting behind Tom Brady for a while.
"I don't really think you can put into words the kind of opportunity [that would be]," he said. "Me and [West Virginia offensive coordinator Jake Spavital] watched a lot of Patriots film and built our offense off a lot of -- obviously a lot of different terminology, but we would see stuff and say, 'We're going to do that.' Tom Brady does all right so we watched a lot of Tom Brady film. The opportunity to learn from a guy like that would obviously be priceless.
Grier added: "We watched a lot of film on them. In 2017 we were very wide-split oriented, which is kind of what Spavs brought to the game at some of the other places he's been that's different. A lot of what we did with the Patriots, we saw they were doing a lot of tighter split stuff. They were getting free releases on guys and working isolations and working diff routes all the way across the field. You get a little more isolation when you bring guys all the way across the field. You don't always get pressed up in that look so it's been interesting to kind of watch how they get guys open underneath. A lot of guys in the Big 12 are in quarters or they're in kind of cloud coverage, deep coverage, and it's hard to get guys open underneath. We watched a lot of their film and kind of picked different things that they were doing to get guys open underneath."
