From my understanding of it, thats right. Ronnie fumble it but chambers recovered it didn't he? I thought it was a partially busted end around?!!?
So if Pit had recoverd you probably would have lost a total of 4 from ronnie instead of just the 2 points. 2 for the fumble 2 for the loss. The odd thing (at least in my yahoo league) was chambers not getting credit for the recover... I figured he should have gotten 2 just like a DB/DL player would get. HTH/make sense
