A player, coach or issue that should be on your radar as training camp approaches.

In some precincts, the Redskins' stunning trade for Donovan McNabb automatically put them in the playoffs. My colleague John Clayton has said he sees the Cowboys and Redskins as the teams to beat in the rugged NFC East. But for some reason, I haven't been converted to the Skins-in-the-playoffs theory, and I'll tell you why.

I don't trust that offensive line one bit.

It's nothing personal. Watching Mike Williams return to football after eating himself out of the league has been heartening. And 32-year-old Casey Rabach does a decent job at center. But in the end, I don't think McNabb can hold up behind this offensive line as currently constructed. It's not like Mike Shanahan can take a beast like Williams and turn him into a cut blocker who opens up lanes for Clinton Portis. And Portis was a much younger man when he was darting through cutback lanes with the Broncos last decade.

The other Williams on the line, Trent, has the tools to be a special player. But he still has to learn the nuances of the NFL game while trying to block DeMarcus Ware, Justin Tuck and Trent Cole. As Bill Parcells liked to say, "this will not go smoothly." It's almost like everyone forgot about the beatings that Jason Campbell took on a weekly basis.

This isn't the McNabb who used to race around and extend plays by 10 seconds or so against the Cowboys on "Monday Night Football." He can slide around the pocket, but it's not like he speeds away from defenders on a regular basis. I'll point to his last two games against Dallas as Exhibits A and B. With center Jamaal Jackson out, the Eagles had to slide players around in the middle. The results against the Cowboys were disastrous.

For now, the Redskins have Artis Hicks lining up as the starting right tackle. To me, that means that Shanahan and his son, Kyle, aren't sold on Stephon Heyer. Most of us expected him to hold down that position. And the Mike Williams vs. Chad Rinehart battle at right guard isn't riveting stuff. Neither player would start for the three other teams in the division.

I certainly agree with the pundits who say the Redskins are better off with McNabb. He'll make Devin Thomas and Malcolm Kelly better receivers. And the combination of Fred Davis and Chris Cooley should be the best tandem in the Beast. But I don't like the thought of putting aging running backs behind a suspect offensive line.

At this point, the Redskins have the worst offensive line in the division and I don't see the Shanahan boys' zone-blocking scheme changing that right away. Could I be wrong about this?

There's always that slight chance.
