First, a H-Back is going to be counted as a RB in that set b/c he lines up at the FB position. That is the same as if the FB went in motion, it just happens more. Second, you have at least 70 plays that counted as two back sets where Gronk couldn't have been in ... what is your explanation for that? How often did we run out of those sets compared to those when a true FB was in?
I get your theory. You start by supposing that we couldn't possibly have been running Felix out of as many true 2-back sets as the numbers say (most in the NFL, among Top 30 rushers). You imagine a situation where a 1-back set might be mistaken for a 2-back set, and then you assume your supposition to be the explanation. It isn't. The fact is, yes, Felix really did run from more 2-back sets on a greater percentage of his runs than any other top 30 RB in the league.
If two players (other than the QB) are lined up in the backfield when the ball is snapped, that's a 2-back set. Doesn't matter whether you're talking about a RB and a FB, H-back, other RB, TE or even WR. When Gronk was injured and missed two games, we didn't change our offense. Scott Chandler played FB.
You ask what about the 70 plays that Gronk couldn't have been a part of. There are about 40 from the two games that he missed, then you have to consider the plays like the goal line plays late in the season when Holland played FB, and all the 2-back sets that included two RB's, or a RB and someone (anyone) besides Gronk.
I went back and looked at all of Felix's runs in the two games Gronkowski missed. If you count
any play in which there were 2 players (besides the QB) in the backfield, whether one of them motioned out of the backfield prior to the snap or not, 78% of Felix's runs (18 out of 23) were from 2-back sets. If you DON'T count the plays when somebody lined up in the backfield and motioned out of it, that number goes down to 74%.
IOW, there was only one play out of the 23 that happened as you described. All the rest were true 2-back sets, as the evidence from season numbers (see post #35) suggested most of them were.

That's a ton of
true 2-back sets, from a couple of games in which the team's only fullback didn't even play.
