That happens on every funble though. We did it when Marve appeared to fumble on the KLM recovery.
Thing is, this was blatant. I was thinking the same exact thing as Syria when I watched the replay yesterday, and I watched it over and over just to make sure I didn't sound foolish if/when I started a thread on it.
The ONLY rationalization i can come up with, Syria, for not calling a penalty, was this: The guy who tackled Floyd as he was going after the fumble, was the same guy who originally tried to tackle Floyd. He got rolled over, and it is conceivable that he didn't know whether FLoyd had been tackled or not, so when he saw Floyd running he MIGHT have thought he was going for the TD, not for a fumble. It's quite conceivable that he didn't know Floyd had fumbled, the way he got rolled over.
Like I said, I looked at it a lot of times, and I can see his defense of "I thought he hadn't been tackled yet, and I was just trying to prevent a TD."
On the other hand, yes, usually anything goes, but it was so blatant I could see the ref throwing a flag in that situation. So I guess I can see both sides of the situation.
