CPU Signs Players To Fill Preseason Roster?
 

I started my franchise last night with the Colts, and everything on settings is set to user. Then I saw that I had some (99?) overall qb NOT named Peyton Manning. I found out that the CPU had signed a crapton of fake players, when I wanted to sign 25 or so vets and ufa's to fill out the roster... Is there a way to stop this?
Thanks
