SANTA CLARA, Calif. (AP) Brock Purdy hasn't had to deal with many rough outings in his brief career in the NFL. That's what made his on a big stage Monday night against the Baltimore Ravens so unusual as Purdy was unable to strike the proper balance of when to take chances and when to protect the ball.Its just not being in the right state of mind as a quarterback, having the aggre sive trigger to make the throw, the big play, but also shoot, dude, you dont want to turn the ball over again, he said Thursday. Its just a sucky state of mind to be in. Thats the learning experience of going back and just taking it and saying every play has a life of its own.Purdy's night got off to a bad start when he forced a pa s in the red zone to Deebo Samuel on San Francisco's opening drive only to have safety Kyle Hamilton step in front of it for an interception. ADVERTISEMENT That came after two big pa ses to George Kittle got San Francisco into scoring position and made Purdy overly aggre sive to fit in a perfect pa Norman Powell Jersey s.Obviously looking back on it, it was not the right decision, wasnt the smart play as a quarterback, he said. "Thats something that I have to grow in, in terms of you make some big plays and stuff, but every play has a life of its own. Now whatever play is next, youve got to play the play the right way and not just feed off the emotion and everything that you felt from the previous plays.Coach Kyle Shanahan described the other three interceptions as more bad fortune than bad decision-making with two coming on deflections that landed in the hands of defenders instead of falling to the ground and another after he was hit as he threw.His biggest concern was the way Purdy played after throwing his fourth interception early in the third quarter.Its tough to play a lot of football after you have four picks and stuff, especially when youre down versus that type of defense, Shanahan said. "I think that was the best experience for him. How to feel that, to know whats happened, to know why its happened, and still have to go out there and sling it around and play. I think thats the best experience you can get from that game. While the bad performance did deal a major blow to Purdy's hopes of winning the MVP, it did little to dampen the confidence his teammates still have in him.They publicly backed him after the game and still believe he can help the team reach its goal of winning the Super Bowl just by playing the way he did in his first 19 career starts. "Im not going to tell Brock how to play the position," Kittle said. "I trust his instincts. Hes done a great job so far the last two seasons. Hes done a great job his whole career. However he wants to play the quarterback position, Im OK with it.Purdy still is at or near the top of the leaderboard in most significant categories for quarterbacks as he leads the NFL in pa ser rating (112.2), yards per attempt (9.7), ranks second in yards (4,050) and touchdown pa ses (29), and third in completion percentage.He has left the past two games with stingers in his left shoulder. He returned after a brief absence in Week 15 against Arizona, but stayed out the final eight minutes on Monday night against the Ravens.He said he isn't concerned that it's a recurring i sue.I was fine the whole game and then that one sack he just got me right, Purdy said. "I landed on it just right for it to go off, but my feeling came back and everything. So, its just I gue s part of the game.
