NFL commissioner Roger Goodell said he is certain he imposed the proper discipline when he suspended Patriots quarterback Tom Brady for the first four games of the season.

In an interview with “Today’’ host Matt Lauer that is scheduled to air in full Wednesday and covers a number of topics, Goodell stood by his decision.

Lauer, in a segment shown on “Sunday Today,’’ asked Goodell, “Can you look me in the eye and tell me as commissioner of the NFL that you feel 100 percent certain that you got this right?’’

Goodell’s response: “Yes, because we went through a very exhausting process with this. We had an independent investigation. We had a federal judge who ruled against it. It went to appellate court. The appellate court at that point in time said, listen, there’s compelling if not overwhelming evidence here. There’s absolutely no question that the destruction of evidence should be considered by the commissioner in the context of this and the process was properly followed. We collectively bargained the process for discipline, we went through that, and I can’t think of an issue that’s been more litigated by the way.’’

Goodell also said that Brady’s prominence as one of the league’s most accomplished players and faces of the NFL played no role in the league’s handling of the case.

“Every player, every team, is subject to the same rules,’’ Goodell said. “We don’t have rules for marquee players and we don’t have rules for marquee teams.’’

Brady will miss the first of four games starting Sunday night, when the Patriots played the Cardinals in their season opener at Arizona.

He is eligible to return Oct. 3, the day after the Patriots play the Bills.
