"Growing up I was a big-time Seahawks fan," Gibson said. "When you grow up in Seattle, you're a hometown kid so of course I loved the Seahawks. But come game time, I'm ready to play no matter who it is."
Gibson had one of the biggest games of his career on Sunday.
He caught three passes for 50 yards and a touchdown, a 15-yard laser of a pass from rookie quarterback Sam Bradford that gave the Rams an early 7-0 lead in the first quarter.
"Great throw by No. 8," Gibson said. "He made an incredible throw, put it right in the hole so all I had to do was catch it."
The second-year pro made another big play late in the second quarter when he turned a quick pass from Bradford into a 23-yard completion that eventually led to a 30-yard field goal by former Seahawk Josh Brown as time expired in the quarter and gave the Rams a 10-3 lead at halftime.
"I thought Gibby did a great job today, especially first half he catches that short spacing route, makes the guy miss and gets us down and we were able to get three points out of that drive," Bradford said. "I think that was huge to go up by seven going into half. So I think Gibby did a great job. He's been playing really well for us the last two weeks."
Gibson was inactive the first two games but has started the last two, wins against the Washington Redskins and the Seahawks at the Edward Jones Dome. He has six catches for 83 yards and the touchdown.
"My biggest thing is consistency," Gibson said. "Once I learn to be consistent, I'll be alright. So I go out there and expect to win on every route and catch every ball."
The Rams acquired the Washington State product in a trade with the Philadelphia Eagles during the 2009 season. In his final eight games with the Rams, which included four starts, Gibson made 34 catches for 348 yards and one touchdown.
Gibson has had more opportunities with the Rams the last two weeks with starting wide receiver Laurent Robinson out with an injury. With Robinson out, Gibson has emerged as one of team's top wide receivers along with Mark Clayton and Danny Amendola.
"Gibson has been doing his thing," Clayton said. "From the first time I saw him, when they started putting him in at practice, I was like this guy is nice. He snags balls and runs great routes. We have to get this guy some routes. For him to come in and be able to contribute is not a surprise from what I've seen in practice. The way I see the game is if you can do it in practice, the game is gonna be easy. He's certainly been able to step up for us."
The 23-year-old has also developed a good connection with Bradford, the team's No. 1 draft pick.
"Sam's a special talent," Gibson said. "The biggest thing with that is making the play when the ball comes to you. I'm going to do my best, keep the chains moving and score touchdowns."
Gibson dropped a pass along the right sideline on the first Rams play of the fourth quarter on Sunday, but on the team's next possession Bradford threw a nearly identical pass along the same sideline and Gibson snagged it for a 12-yard gain and a first down.
"I have confidence in him," Bradford said. "I knew that if I put it there Gibby was going to make the play and that's what he did."
