On that topic, I believe we discussed this before, and I believe that we were in agreement on this, but I could just be bringing in outside rules to this league. I do not believe you can sign a DL guy from the free agent list and call up a farm player for that guy. The idea being, last year it would be easy to go find some DL scrub to sign so that Trout could have been played all year for "free."
Also, I'm not sure I totally understood the Hart thing. How would you have picked him up without signing him?
