And you were showing a hint of reality. That didn't last long.
First, It's not really a 2 TE offense. We use 3 WR's consistently, and 4 some of the time, which we couldn't use if we were using 2 TE's all the time. 2 TE's are just another of many packages the team uses, not the standard.
Jarwin did not play 50% of the snaps over the year. He played 47% of the snaps in the 8 games that he played. Schultz played 81% of the snaps over the season, so he wasn't even every down. The others just had a small taste of the overall playing time.
As for 2020, time to move along. It's rare for anyone to reach a top level in his first year as a starter, so it's ridiculous to ignore his 2nd year as a starter and act like the 1st one is his standard. Even so, he was about 11th in TE production in 2020 as I recall, and he progressed in his 2nd year starting. Judge him by that.
