Only rostering 1 TE and not making adjustments when they are on a bye, is it tanking?

I'm in a money public league (managed by a third party) where I am 1 of 3 teams who started 0-4.

There is 1 unlucky manager (team A) who lost the 4 matchups with a good team, so I don't think the team is a threat to the #1 overall pick, there is me who went half young half old on the startup and now I'm stuck in purgatory, and then there is a manager who went super young in the draft and doesn't have any bright spots besides egbuka on his team (team B).

I think I'll win less games than Team A, but Team B has a good chance of going winningless.

However, he has just 1 rostered TE, which is on bye this week.

If he doesn't add another one through waivers, is it illegal tanking? There is the argument that he didn't want to lose any of the other players, but idk, seems sketchy.

Bylaws state that any week that a team tanks, a W is added to their Win column for the draft order, so there is a consequence if it's categorized as such.

Thanks in advance!
