If you take a look at the video that's part of this link featuring ESPN investigative reporter Mike Fish, he makes an interesting point about the taping. Although it appears there is no new news here, the fact that the older tapes can now be viewed (remember, the league destroyed the more recent spy tapes) raises again the issue of competitive advantage the Patriots may have gained. Fish points out that if the Pats didn't gain a competitive edge (the league has said that the taping did not impact on the outcome of games), then why would the Patriots have continued to refine their techniques as they went along? It would appear to be an awfully time-consuming exercise if it had no value. Would Belichick waste his staff's valuable time on work that had no payoff?
