A 7 Day Contract is a 7 Day Commitment, right? I seem to recall somebody dropped a player before 7 Days, but that's not allowed, is it? Meaning: If you want the luxury of utilizing 7 Day contracts, then you need to stick with the 7 days. You can't just drop the player and pick up the hotter hand or something like that.
Is my question making sense? I just don't recall seeing that in the rules. I'll double-check now that I've typed out this post.
