for setting up a sting operation, absolutely!
Ask yourself: did the Colts and the NFL want to
1) ensure that no deflated footballs were used in the game,
or
2) ensure that, if possible, the Patriots could be charged with deflating footballs
If the answer is #1, the NFL would have done what Paul Tagliabue says that he would have done: call up the Patriots, tell them of the non-specific complaint from Grigson that could be attributed to "chatter" and no source or no hard information, and warn them that they (the NFL) would be watching.
If the answer is #2, then you end up with deflategate, aka framegate.
Sting operation....frame gate. You are beyond delusional at this point. You are just like so many kids today and sadly, you are far from a kid. You refuse to own up and be accountable for the wrongdoing that your team obviously did. You are trying to place blame on everyone except the actual culprits. It's not the Colts' fault that Brady was cheating again. Stop making excuses.
