I just read something that provides the magic words needed to assess Ferguson.
Someone called him a “move TE.”
That’s less of a pure inline blocker who lines up and is, basically, when run blocking, another O-lineman.
A move TE, you put in motion and move all over the formation whether it’s run or pass. They often run block on the move (wham blocks etc) and then of course also use motion to set up pass routes. So it helps not to think of Ferguson as a a traditional TE, who tend to be inline blockers in the run game, but to instead think of him as a move TE, who tend to play like big, athletic wide receivers that line up anywhere–inline sometimes but also out wide, in the slot, or behind the LOS.
