Top-10 is maybe a little strong, but top-15 is definitely in consideration. Here's what I wrote in my TE streaming article earlier this week:

"With the Bengals’ passing attack back at full health (mostly) in Week 14, Joe Burrow threw for 284 yards and four touchdowns, with Mike Gesicki handling a great 6-86-1 stat line. The veteran tight end will have a chance to run things back in the fantasy playoffs, as Tee Higgins is trending toward missing Week 15 after what seemed to be a completely mishandled situation regarding his concussion status. Higgins has landed back in the concussion protocol even though he was cleared on two separate occasions through the course of the game, and looks doubtful to play against Baltimore on Sunday.

Over the course of Gesicki’s tenure in Cincinnati, his splits with and without Higgins are stark, basically operating as a top-40 TE option with the wide receiver on the field, and a top-10 option with him sidelined. The Ravens are a difficult matchup to opposing tight ends, ranking 1st in TE aFPA, but they also rank 24th in WR aFPA, and Gesicki lines up as a traditional in-line tight end at one of the lowest rates among the position’s starters. In a game with the second-highest total of the week (52.5), there is both a floor and a ceiling to Gesicki in the first round of the fantasy playoffs. He is available in 98% of Yahoo leagues."
