First of all, they didn't deny everything. What the Patriots did deny was the things they did not do. Like "deflategate" or in this particular instance - taping the Rams walk thru. Spygate, taping of the teams signals, they most certainly admitted to, and apologized for. Both the owner and the coach. But hey, lets not let facts stand in the way of a good story...
As for the walk thru tape, here ya go:
