you do realize that last season was only the second season for Shotty right? also that every WR on the team has only one or two years in the league, that he had 2 second year RBs and three rookies, that he somehow managed to win 7 games even though he was using KC who isn't a very good throwing QB in more than half their games, what do you expect when you have mostly first and second year players in an offense they have only run for 2 years? you do know that most WRs take 3 or more years to start being really productive right?
he was forced to dumb down the offense because of that youth IMO, once TA started to catch on, did he not find more creative ways to use him? if he was to put too much on these young players it would hurt their development IMO.
