Thoughts on how to improve my dynasty team?

12-team dynasty league full ppr & individual players get special teams pts (6 pts) if they score on a kick/punt return

I was the highest scoring team in my league and ended the reg season 11-2, but sadly lost in the first round of the playoffs. Is there anything I can do to improve?
