In his first 14 games in the NFL, Bradford has already lost more games (eight) than he did during his days as a starting quarterback in college.
"I don't like losing," Bradford said on Wednesday. "It's not something that's enjoyable at all, but at the same time it's a little different than college. In college, you lose one or two games and you're completely out of the national championship picture.
"In this league, we've lost eight times and we've still got a chance to make the playoffs and make something happen, so you can't get caught up in that. Obviously we'd like to have a couple more wins, but the fact that we're still in it … we've just got to keep moving forward."
The Rams are 6-8 and tied with the Seattle Seahawks for the top spot in the NFC West with two games remaining, against the visiting San Francisco 49ers (5-9) on Sunday and then at Seattle the following Sunday.
And the playoff fate for St. Louis may be determined by Bradford, who has struggled in recent weeks after a strong start to the season.
On Sunday, he completed 21 of 43 passes for 181 yards and two interceptions and a quarterback rating of 40.9, which was his lowest of the season.
For the season, Bradford has completed 59.4 percent of his passes for 3,065 yards, with 17 touchdowns and 14 interceptions, and a quarterback rating of 75.9.
"Obviously the past couple weeks I haven't played as well as I would like to," Bradford said. "It's frustrating at times, but like I said earlier, you can't get caught up in the past. Those games are over. I come in on Mondays, I learn from those mistakes, and move on to the next game. That's what I did this week. I wouldn't say that defenses have done anything different. It's me just not being as clean in my reads as I need to be."
Some of his teammates on Wednesday were asked if Bradford had hit a "rookie wall."
"Nah," wide receiver Danny Amendola said. "I don't believe it. He's a good competitor. He's a strong-willed and minded person. He's a great player."
Center Jason Brown said: "Sam is poised. He's calm. He's assertive. He hasn't said much but I can see it in his face that he doesn't like being on the ground and I don't like him being on the ground."
"He's handled this rookie season as a true pro," Brown added.
