Many questions about Brian Waters

IRVING, Texas -- Cowboys guard Brian Waters practiced for three days this week and worked with the first- and second-team units in pre-practice work. During team drills, Waters was working on his conditioning.

While Waters said he knows the offense, his availability for Sunday night's season opener against the New York Giants appears remote. David Arkin most likely will be active on the 46-man game-day roster as a backup guard along with center/guard Phil Costa. The Cowboys will keep at least eight offensive linemen active for the Giants. Waters isn't ready to play just yet, and by saying he could play, is more of a competitive thing against Sunday's opponent. It's sort of like the Cowboys listing injured defensive end Anthony Spencer as doubtful on the injury report despite not practicing all week.

The Cowboys are just messing with the Giants.

Waters said he still needs to get to his playing weight in the 300- to 315-pound range and it's not determined how long that will take.

"I think we go day to day and see how he feels and see how much more he can handle," offensive line coach/offensive coordinator Bill Callahan said. "I know we’re working him a little bit more later in the practice with the training staff and with the strength and conditioning staff trying to work on his metabolic workout a little bit and try to get him acclimated to drive series where he can [go] six plays or eight plays or whatever it may be."

It's hard to believe Waters would play against the Giants Sunday night after not playing for more than a year.

The biggest issue is not whether or not Waters would play Sunday night, but can he get ready for the Week 2 game at Kansas City. And what happens if the current line plays well against the Giants?

Do you keep that line in for the Week 2 game?

Is Waters still better than Mackenzy Bernadeau at right guard after not playing for more than a season?

There are many questions regarding Waters right now; his résumé is filled with positive plays, awards and praise.

Will that continue?
