Proving Ground: Robert Brewster

Fifth in a 10-part series focusing on young non-starters who have a lot to prove during training camp (series):

More than a year after he was drafted in the third round, offensive tackle Robert Brewster is still waiting to make his first real impression on the Cowboys’ coaching staff.

Oh, they’ve gotten to know Brewster. They like the approach he took to rehabbing after tearing a pectoral muscle last summer. They’re pleased with the way he’s worked to change his body, which is still a blubbery work in progress.

But they’ve yet to see him put on a pair of shoulder pads. That will finally happen in training camp.

The hope for the Brewster, who is listed at 6-foot-4, 320 pounds, is that he will develop into Dallas’ right tackle of the future. It’s also possible that he could move inside to guard, where Kyle Kosier is entering the final season of his contract.

But Brewster isn’t guaranteed anything. If he doesn’t perform well in training camp and the preseason, it’s possible that he could be pushed off the roster by sixth-round pick Sam Young.
