The NFL has made a couple of rule tweaks that have the potential to be fairly significant down the road in the 2012 season. The trading deadline has been moved to after Week 8 and teams can now re-activate one player from the IR if the injury was suffered after September 4. Personally I think the trade deadline should be even later. I'd love to have "buyers" and "sellers" like the rest of the pro sports leagues after about 10-12 games. (It would have made the 2011 Vikings season a lot more interesting, that's for sure.) What do you think? Are the new changes good, bad, or too insignificant to have much of an impact?
