RENTON, Wash. -- It probably has come down to this for quarterback Terrelle Pryor: He needs to play well against his former Oakland teammates in the final preseason game Thursday night to secure his roster spot with the Seattle Seahawks.

In other words, Pryor might need to show the Raiders they were wrong to let him go if he hopes to prove to the Seahawks they were right to trade to get him.

The Seahawks gave up a seventh-round draft choice to get Pryor, not exactly a big risk. But whether he’s worth a roster spot as a third quarterback remains an interesting decision that has many fans divided on their opinions.

“We’re going to go through next week and see what happens," Seahawks coach Pete Carroll said after Friday’s 34-6 victory over Chicago. “It’s real important. Next week will be a good chance for the other guys to play again. They did not get a great look [Friday] and didn’t get one last week, either.

“We’ve had a couple games where the QBs didn’t get as much action as we’d like. Next week’s really important for Tarvaris [Jackson] and Terrelle and B.J. [Daniels], so we’ll see how that works out.”

Jackson appears to be a lock as Russell Wilson's backup. He’s a veteran who knows the offense and is highly regarded by his teammates. Daniels, a second-year player from South Florida, is the forgotten man in this scenario and a long shot to make the team. But he has thrown the ball well in limited opportunities and he has good scrambling skills. Daniels could end up back on the practice squad.

So this battle is really all about Pryor. He has looked good at times and not so good at others. He almost led the Seahawks to a game-winning drive late in the fourth quarter of their preseason opener at Denver before rolling out and throwing an interception in the end zone. But things could have turned out differently if rookie running back Demitrius Bronson hadn’t dropped a swing pass for a probable touchdown one play earlier.

Pryor showed what he does best one week later with a 44-yard TD run against San Diego, a run that few quarterbacks in the NFL could accomplish. Pryor (6-foot-4, 235 pounds) used his blazing speed and athleticism to reach the end zone.

However, Pryor has struggled throwing the ball the last two games, going 1-for-6 for only 10 yards. Pryor had only two throws in garbage time Friday night against Chicago, but one of them was an interception.

His totals in three preseason games: 10-of-22 for 147 yards and two interceptions. He also has rushed for 85 yards on 12 carries.

Starters typically don’t play much in the final preseason game, so it’s likely the Seahawks will take a long look at Pryor in his return to Oakland.

If Pryor doesn’t play well against a team as weak as the Raiders, a team he surely has incentive to play with emotion against, it could mean his demise in Seattle. If he does play well, the Seahawks might see a brighter future for him, believing his athletic talent is worth the roster spot as a long-term investment.

So Pryor returns to Oakland with something to prove to the Raiders, Seahawks and himself.
