That's because he's about to visit Chicago to face the team he played for last season. McCown played the best football of his career for the Bears: Filling in for an injured Jay Cutler, he threw for 13 touchdowns with just one interception. That performance was enough to get McCown a two-year, $10 million contract and a starting job in Tampa Bay.
McCown said his momentum from last year went away at the beginning of this season. He has said he was pressing too hard in the first three weeks, throwing two touchdown passes and four interceptions before suffering a thumb injury that kept him on the sideline for five games. But since returning to the lineup two games ago, McCown said he feels like he did during his run as Chicago's starter.
That was especially evident on Sunday in Washington. McCown completed 15 of 23 passes for 288 yards and two touchdowns as the Bucs (2-8) snapped a five-game skid.
"I don't know that I felt that way the first few games," McCown said. "That's how I envisioned it. That's how I felt when I was playing last year. I felt more calm, and [quarterbacks coach] Marcus [Arroyo] and I are on the same page with the plan and just where he's at as a playcaller. That brought me a lot of peace. That's more what everybody envisioned."
Sunday's performance was exactly what the Bucs envisioned when they signed McCown.
"If you look at what he did last year and his body of work when he was given a chance, he was very impressive," Arroyo said. "I think he's capable of doing that game, and that was a great game last weekend. We've got to try to find a way to do it again and again."
McCown said the arrival of coach Marc Trestman in Chicago last year helped elevate his game.
"Just from the standpoint of having someone on the offensive side of the ball bring his kind of expertise," McCown said. "You get different things from different people in your career, and I've had tons of coordinators, some really good ones. But every now and then, you click with somebody that sees it the way you see it. As a player, the way they call a game or the way they see the game, it kind of hits your brain the same way. For me, I think that's what allowed me to play at the level I played at for Marc."
Bonding with a coach wasn't the only positive McCown took from his three seasons in Chicago, which included two years playing for current Bucs coach Lovie Smith.
"Especially when I first got there in 2011, I liked how that locker room was," McCown said. [Linebacker Brian] Urlacher was still there. You could just feel the closeness of that group of guys. It's very rare that you get to be in those kind of locker rooms when you have groups that have been together like they have. I mean, you're talking about Lance Briggs and Peanut Tillman have been teammates for 10 years plus. That's unheard of. It just doesn't happen very much in this league.
"When you get in a locker room like that where you have guys that have been teammates that long and observe their relationships and how much they appreciate each other and their friendship and watch how it plays out on the field, I think that's what I look back on my time there the most -- how important those relationships are in that locker room."
