At this point, the NFL is just trolling their fans, right?
The league claims they had been investigating for 7 months, but there were reports over those months that not much had been done. For example, they hadn't interviewed Peppers, Harrison and Matthews yet, but we're to believe they spoke to Manning without anyone hearing about it and completed all of their research.
I guess that means we can expect clearance for all the other players involved before too long. As far as we know, they didn't have PEDs shipped to their home. Even if they did, that doesn't mean anything, according to the NFL.
