Didn't say he was Jimmy Graham.
The 2 TE positions are definitely different. You can believe what you want. I'm just offering to give you information that you don't currently possess.
It's similar to how slot WR and outside WR are different. If Beasley missed any time and Dez/TWill were playing they would likely try Lucky or Dunbar in the slot over Butler even though Butler is the top backup on the outside.
Jesus Christ. Now there's no such thing as an outside receiver playing in the slot. This keeps getting better.
Okay, I'm going to humor you. Let's say that this offense does employ two radically different tight end positions. In that case...
1) If all four TEs were healthy and Witten went down, would Escobar take his place over Hanna and Swaim, or would one of those two "switch positions" while Escobar stayed on the bench?
2) If your answer is that Escobar would play, then are we to assume that Witten also can't play the other TE position as well as Hanna or Swaim? What is preventing a sub-package with Escobar at "TE #1" and Witten at "TE #2?" Aren't we supposed to assume that having Witten and Escobar on the field together is better than Witten and Swaim?
3) Why does Lucky Whitehead have three times as many snaps as Escobar? Using the same logic, shouldn't having Escobar on the field be better than having Whitehead on the field? Why does Whitehead have so many sub-packages while Escobar has fewer than 25 offensive snaps on the year?
