ON team page, under Team Stats:
" 'Turnavor' Margin"

"Turnover" is spelled correctly within the League Home/Team Stats link tree.
*edit ex post other posts (hehe): "Turnover" is not the correct word for this stat, either.
"Upon Further Review" it should be "Turn Overs."

Additionally and though I'm not sure how the item is actually stated in RL NFL stats/boxes:

"A turnover (noun) is an event where the offensive team loses possession of the ball to the defense before scoring or punting. 'Turn over' (verb) describes the action of losing that possession."

The stat is about gaining/losing possession - so *should* it be "Turn Overs?"

Personally, I really love a fresh, flaky, easy to pull apart apple trunover lightly covered in vanilla frosting with a cinnamonamonamon dusting.
*grins*

"he turned it over"
"He turned over the ball"
- me thinks this implies the stat should also be listed as "Turn Overs."
