It comes down to whether Smythe retains the #1 TE position. The last two seasons (among the positions from that list) the #1 TE got the most snaps, followed by the #3 WR , then the #1 FB. But the #2 TE would be the bottom of the list. If Smythe is the #1 TE then that order probably remains. If Jonnu Smith beats him out then Smythe drops to the bottom.
IMO we should be hoping that Smith is an upgrade at TE. If he is a good enough blocker then being able to motion him between an inline blocker and #3 receiver option would make our offense tougher to set an alignment against. I also think our offense would be more variable, more unpredictable if Ingold took on more snaps through a combination of FB/H-back while Smythe became TE #3. Thirdly, it would be great if OBJ and Malik were effective enough that our 3 and 4 WR sets were used more. There are more combinations I could think of that furher skew/change this year's snap count disbursment. Some of those include Smythe, but ideally we'd add a few that don't. (We simply didn't have many players that were a better option the last two seasons).
So bottom-line my guess would be Smythe. He improved greatly from two years ago to last season. He may still be the best all-around TE. But I'm hoping the additions and development of our other higher ceiling players upgraded our talent to the point that Smythe is relied on less.
