SANTA CLARA, Calif. -- Observed and heard in the locker room after the Chicago Bears' 28-20 win over the San Francisco 49ers.

Brandon Marshall admitted that after a few days of matching up with rookie Kyle Fuller during training camp, the receiver found himself spending time studying the cornerback to find ways to beat him. That’s how much of an impression Fuller had on Marshall. In fact, quarterback Jay Cutler said, “You’d think [Fuller] has been in the league five or six years from the way he carries himself.”

Fuller performed like it against the 49ers, picking off two passes, including the interception that allowed the Bears to pull ahead.

Christmas tree: Tight end Martellus Bennett finished Sunday night with 37 yards receiving on a team-high seven receptions, and joked in the locker room after the game that he was a “true West Coast tight end.” With reserve Matthew Mulligan dressing next to him, Bennett goaded his teammate to explain the tight end’s route tree.

Mulligan refused, joking, “Don’t get him started.”

Turns out, Bennett says his route tree is different than most tight ends in the NFL. He’s got a “Christmas” route tree.

“Other tight ends, their route trees are plastic and come in a box,” Bennett joked. “You’ve got to go out and cut mine down.”

High-fives: Immediately after the locker room opened, Bears general manager Phil Emery could be seen high-fiving players on his way through the room. Emery is usually low key and doesn’t show much excitement, but Sunday night obviously was different.
