The Washington Redskins may be done with the two-a-day practices of training camp, but they still have things to nail down as a couple of starting jobs -- as well as key backup roles -- remain up for grabs.

“We’ll be evaluating all the way up until Week 1,” offensive coordinator Kyle Shanahan said.

The starting quarterback position is most definitely not a question area. And for once, it appears that the offensive line is stable (as long as right tackle Jammal Brown’s hip holds up. If not, Stephon Heyer’s your starter). And the secondary appears to be set. But otherwise things remain rather fluid. Here’s a look at some of the key areas that must be addressed in the remaining three weeks of the preseason:

Wide receiver -- Santana Moss is the No. 1, and so far, none of his younger teammates have been able to wrestle the No. 2 receiver job away from 39-year-old Joey Galloway, who has consistently been getting separation from defensive backs during training camp. Can Galloway, for whom the New England Patriots and Pittsburgh Steelers had no use last season (three games, seven catches) really be the second-best receiver on this unit? It certainly looks like it. Anthony Armstrong has frequently been worked in as the third receiver, and Roydell Williams gets some first-team run here and there. But Devin Thomas -- the player the Redskins need to finally live up to his potential -- is stuck with the second- and third-teamers with rookies Terrence Austin, Brandon Banks, Shay Hodge and veteran Bobby Wade. Is that Shanahan’s motivational tool?

And then there’s Malcolm Kelly, another second-round draft pick from two years ago that has yet to deliver, but now needs to get his hamstring right so he can finally show he’s worthy of making the team. The Redskins likely will carry only five to six receivers. Performances in these three games will be the determining factor. Mike Furrey has been placed on injured reserve after suffering a concussion in training camp and not being able to return, so that helps with the numbers game. But Redskins coaches -- and fans -- want jobs to be won, not awarded by default.

Running back -- Clinton Portis is the starter, and it appears Larry Johnson is the No. 2, but Redskins coaches insist nothing has been determined. Willie Parker’s first- and second-team touches have been limited. Meanwhile, second-year back Ryan Torain and rookie Keiland Williams are getting every opportunity to show what they can do. The Redskins are more likely to carry four running backs than five. Who makes the cut, and who gets the nod as the third-down back?

Defensive line -- The ends appear to be set with Adam Carriker and Kedrick Golston manning the left and right spots, respectively. Nose tackle? One would’ve thought by now that Albert Haynesworth would have supplanted Ma’ake Kemoeatu as the starter. But Haynesworth went through only five of the 18 full-contact practices in training camp, and his status for Baltimore on Saturday is a mystery. How in the world is this soap opera going to play out? Haynesworth finally getting serious and taking over at nose tackle? Or, bumping out Golston at right end and Kemoeatu remaining at nose tackle? Or, just being used as a grossly overpaid backup NT/DE? And who are the backup DE’s? Vonnie Holiday and Phillip Daniels appear to have the edge. Jeremy Jarmon is still working his way back into the groove after having ACL surgery last season.

Outside linebacker -- Andre Carter appears to have the edge over Lorenzo Alexander at the left outside linebacker position. After working exclusively with the first team last week and starting, Carter was supposed to switch with Alexander this week, but Alexander was slowed by some foot/ankle soreness that forced him out of practice Monday. He has returned but remains with the second unit. Carter still has work to do as he converts from DE, and he admittedly looked lost a few times in last week’s game. But coaches like the job he’s doing. The other linebacker spots -- London Fleter and Rocky McIntosh at the two inside positions, and Brian Orakpo at the right outside linebacker position -- are set.

Secondary -- Defensive coordinator Jim Haslett continues to praise cornerbacks DeAngelo Hall and Carlos Rogers and safeties LaRon Landry and Kareem Moore. But who will be the backups at CB? Phillip Buchanon appears to have one spot locked up, and would be your third CB in Nickel packages, and Kevin Barnes, Justin Tryon and Byron Westbrook continue to battle for the other.

Special teams -- Who’s the return man? Thomas is slotted at No. 1 on kickoffs, but won’t hold that job for long if he botches another return like he did last Friday. Brandon Banks can help his case on punt return with another strong performance or two. Terrence Austin looked solid last week as well. Long-snapper is the other battle, where James Dearth has been taking the first-team snaps over incumbent Nick Sundberg, who struggled all of camp, but appears to be doing better now. And although fans don’t care as much, guys like Austin, Roydell Williams, Armstrong, Thomas are auditioning as gunners on the punt team. Strong play there could be a determining factor on who gets the last receiver spot or two.
