Oh, sure. Invisible Man whose super-power is never once getting on the field on game day is going to overtake the dude with 265 career tackles who looks to have a chance to get 5 or 6 sacks this year because he will be rushing the passer more in Fangio's defense.
And, of course Wolfe didn't need his "greedy wife" to tell him anything. Like all players, he knew perfectly well this is his final year and that he has not got any extension worked out with the Broncos. There's a good chance he could be gone next year, but he's confident that he's such a good fit with Fangio's defense, that Fangio will go to John Elway and tell him to re-sign Wolfe.
Did you think he's dumb enough he didn't know how many years are left on his contract or what amount of money he might make in his next one? His agent will have talked about all that to him in detail.
And even if he doesn't, Wolfe realizes that a 5 or 6 sack season in Fangio's defense would get him serious attention from other teams as a FA next year. Team leader, super bowl champion contributor, tough competitor. What's not to like? He's looking to cash in and a good season heading into FA is just what the doctor ordered for that final big contract!
