I'd be pissed at the commish and demand my money back after pulling a stunt like that. That's complete BS.
TJ should work as a #2 with that roster, but you do need help there for sure.
Look at the titans TE also (Troupe and Kinney) as they are available in most leagues. Troupe should catch more as the season progresses.
I would trade Parker for a solid #2 straight up but having that many WR spots required to start is going to make that tough. I would normally say try to target somebody like Driver, Wayne, or a Ward but I don't know if you will be able to get that with the number of required starting WR's.
I wouldn't play in that league next year with that commish. That is complete BS.
