There is no way Everett gets a third round comp pick. According to overthecap in the 2021 pick cancellation chart 14,000,000 was the cut point for third and fourth rounders. Whereas Everett could be a starter somewhere he is not one of the best TEs in the league. Only Kittle and Kelce make 14 million + a year. The next bunch is around 9-10 million. If someone really likes Everett he may get a deal around 7-8 million, and put him in the top 10 players at the position. He is not even the top TE on the market. That would be Hunter Henry and then Jonnu Smith. He is in a bunch with some older TEs Gronk, Olsen, and Cook.
