I didn't read most of this thread so I don't know if it's been posted yet, but here is how MFL is handling it:

1. How is the week 13 Meachem Fumble Recovery TD after an Interception in the Saints game being scored?
Answer: At the end of the first half of the week 13 game between the Redskins and Saints, Kareem Moore of the Redskins intercepted a pass from Drew Brees of the Saints. During the interception return, Robert Meachem of the Saints stripped the ball from Moore, and ran it in for a TD.
As mentioned in our Strange Plays FAQ, we've always scored this type of play as a 43 yard "Offensive Fumble Recovery TD" for Robert Meachem (see the "Offensive Fumble Recovery TD Following A Turnover." section). If your league wants Meachem to receive the points for this touchdown, then you'll need to make sure the "Offensive Fumble Recovery TD" rule is defined in your scoring rules for the WR position.
If your league wants to score this play differently than how it shows up in the stats, then your commissioner would need to use the "For Commissioners > Adjust Scores and Standings > Player Score Adjuster" screen to add or subtract points to Meachem or the Saints Defense as needed.
Note: This play is NOT scored as a Defensive Fumble Recovery TD for the Saints Team Defense position, since their defensive unit was not on the field during that play.
One common "urban legend" we've heard about this play mentions "the NFL scores this as a defensive play". While that sounds like a convincing argument, unfortunately, it's not correct. The gamebook from the Saints/Redskins game most clearly indicates this, where, on page 5, it has a "Final Defensive Statistics" page. Note the statistics for Meacham's tackle, forced fumble, and fumble recovery are listed under the "Misc" heading, and not under the "Regular Defensive Plays" heading. So while the Saints, and Meacham, were in fact defending their goal at the time he stripped the ball away, the Saints offensive team unit, and not their defensive team unit, were on the field at the time of this play, and therefore, we feel that most leagues will not want to score this as a touchdown awarded to the Saints "Def" position. In short, the "Def" position is simply an invention made up by us fantasy footballers for the benefit of our hobby, and not anything that the NFL officially recognizes.
Note that for what it is worth, the last time this type of touchdown occurred was 6 years ago in 2003 when the Buccaneers threw an Interception, which was then fumbled and then Keenan McCardell recovered it and ran it in for a TD. So this type of play is very rare, but it was scored the same way the last time it happened.
For a more detailed discussion of special plays like this, please see our Statistics Lifecycle FAQ, specifically the "A Special Note About 'Miscellaneous' Plays" section, which goes into detail on this general topic, and the responsibility that you and your league-mates have in deciding how plays like this are scored before they actually come up in a game situation.
ETA - I don't know why that link isn't working but I got it from the 4th post in
