Tet easily. I like Warren, but the positional value difference between them is immense. The highest paid TE now makes as much as the 22nd highest paid WR.
I think Tet is like a Michael Pittman, Drake London type of player. Pittman plays for $23M a season, and London's probably going to get high 20Ms to 30M per season whenever he re-ups.
For comparison, George Kittle plays for $15M a year, Kelce makes $17M/yr, and Trey McBride just resigned for $19M/yr. So in terms of salary, Warren would have to become a special player and hit his best-case ceiling to even reach Tet's floor.
