As Patriots TE Rob Gronkowski's playing time has increased upon his return from a torn right ACL, the Patriots have trended more toward multiple-tight-end groupings, which makes sense. Specifically, the Patriots seem to have found something that works for them -- going empty with the 2-WR/2-TE/1-RB grouping with Gronkowski and Tim Wright at tight end, which in a lot of ways could be viewed as a 3-WR package of sorts because of Wright's presence as more of a pass-catching tight end.
With a lower percentage of three-receiver packages, it has reduced the playing-time totals for pure slot receiver Danny Amendola. But as we saw Thursday, he's still contributing in that niche role (as well as a kickoff returner).
One could also draw the conclusion that inconsistent play along the offensive line has contributed to fewer three-receiver packages. By playing with a second or third tight end instead of a second or third receiver, the Patriots are devoting more resources to the line of scrimmage. Everything starts up front.
The story goes on to say that every offense needs something to hang its hat on and perhaps the Pats found it. Gronk's health has been key to this and multiple TE sets are allowing QB Tom Brady to takes shots down field while at the same time bolstering things up front. The Pats are used multiple TEs 57-percent of the time this season.
