I'm really bad at trades. Like, reallllly bad

Bye-week aside (I already counted this loss), I am looking to upgrade my WR core. They are bad. Thomas and Allen have done nothing for me and the rest are just…a miss. And I have a lot for some reason. I wanted to leverage Martin after he got back but holy cow, could he be worse? Like, whoever keeps buying him must be BSU alumni because there’s no other reason to have him. What do I do?

I need to trade and upgrade but I am SO bad at trades. I never know what’s good and what’s bad. Any advice would be appreciated. I haven’t topped 80 points two weeks in a row now, so I’m obviously doing something wrong.
