Tampa to win. It is only acceptable to root for the division winner to better our WC chances; never acceptable to root for the division leader while we are still in the race. Most of you are thinking too tinily.
Do you see Atlanta losing 5 more times on their schedule?
Do you see the Saints not losing again this season?
If both of these are yes, you can pull for Tampa.
If either is no, you need to pull for Atlanta.
Easy choice, Atlanta to win. At this point in the season, you just get in. The last Wild Card is in play, not the division.
