I've often thought that the whole move/flex TE "need" to go back to 2TE sets was nothing but a made up piece of fan fiction.
We can take advantage of the hurry up, the ability to switch back and forth from run/pass and vice versa, a better blocking game than Hernandez, and a great red zone target. On top of that, we would also cover our asses if/when Gronkowski misses any time in the future. After watching 3 years in a row of postseason inefficiency due to the loss of our main TE, this definitely should be a concern.
