16 team, 9 cat roto. Two-center league where I'm weak at the position (my starters are Al Horford and Cody Zeller). I have these three on my bench:

Richaun Holmes
Nerlens Noel
Mitchell Robinson

And these two are available:

Jordan Bell
Thomas Bryant

1. Would you drop any of the three I own to pick up either/both of the two available?
2. How would you rank the five in terms of rest-of-season outlook?
3. If Zeller misses more games and I have to plug someone in, which of the five is most startable right now?

Thanks!

EDIT: You know, Kevon Looney is available too and will be getting some of the Damian Jones minutes along with Bell, so you can rank him in there too if you like.
