Really hard to evaluate the trade without knowing if its roto or h2h. In a 10 team NL only league, there's less than 2 closers to go around between the teams. So depending on the distribution and the type of league, Cordero could either be close to worthless or gold. Molina is a solid C in an NL only league and his value depends on whether you're playing 2 Cs. In a 1 catcher league, his value isn't that great unless you expect him to play 145 games again.
On the flip side, Jimenez had a very good second half, but has 1 good and one bad start so far. He should be somewhat erratic this year, so I think he has less value in a H2H league. Schafer is a legit 12/20 threat, but he'll have a hard time cracking the top of the lineup to rack up the runs and drive up his value. Again, depending on the league and your team, those steals could be gold.
