I agree with Steve Smith over Percy Harvin. You've got a solid team and honestly you should walk away with this one no contest. In the leagues I play in a team that goes 6-8 has no business or no chance of even making the play-offs.
Granted I only played in two leagues with RL friends and they are both over. One is a keeper league (keep 3 players) and the other is standard almost like yours, except only 2 WR's slots, then a RB/WR flex and a TE/WR flex.
In the "regular" league I finished 10-3 and won the championship game last week. I was pretty stoked because my keeper team fell apart.
So best of luck and I'm going to go ahead and congratulate you on your championship, because I don't see him winning, even with my beloved Stafford on his team. PS his team name is hilarious.
EDIT: Good luck, let us know how it ended! My boy Stafford put up a BEASTLY loss today!
