The biggest NFL TV signing of the offseason, NBC’s rookie Mike Tomlin, dropped one of his Tomlinisms almost immediately as he assessed the Super Bowl-winning Seattle Seahawks before their game against the New England Patriots.Tomlin described how defending champions can be either “hungry or driven.” He then mentioned a “tapeworm.” His overall point was that as the hunted, not the hunter, you have to want it more.While it was a bit confusing, he could have been detailing his move from Super Bowl-winning Pittsburgh Steelers coach to studio analyst.Though Tomlin brought much-needed gravitas to the remodeled “Football Night in America” in his regular-season debut, his performance left more of a question than a verdict: To borrow his terminology, does he have a “tapeworm”-like drive for TV or not?For sure, Tomlin has a lot of potential. His on-air presence is exceptional, as you want to know what he is going to say. He looked pretty comfortable on set and had the signals down on where to look as Maria Taylor quarterbacked a revamped NBC pre-game show that will be on the road every week.Tomlin was a bit tepid, as it definitely wasn’t fully clear whether this is just a timeout in his coaching career or if he’s going full John Madden, leaving his whistle behind for good for TV. He provided some insight, but it was a little see-no-evil, without a “Wow” moment.The Seahawks’ injuries on defense? Well, that could be a “blessing in disguise,” Tomlin decided, as Seattle’s head coach Mike McDonald might be inclined to keep the game plans simple and players can be looser. Half-full stuff, for sure.Tomlin is just 54, even though it feels like he has been around the NFL forever. When Taylor introduced Tomlin at the top of the pregame, she teased that the crew will have to tame Tomlin’s urge to put a coach’s headset on.
