2015 seems particularly harsh. Perhaps it because notable marquee players have been lost to season ending injuries. IDK Is the trend higher than past season's? Is it because of the practice limitiations? I have no idea but the lists I'm looking at seem excessive compared to past seasons. Look at this list, mind numbing if you are fantasy football player.
