This makes sense only if they saw a significant drop off in his performance in camp. They haven't hesitated in the past to play guys through the ends of their contracts, even if they didn't have intentions to resign them. There was talk last year that he wasn't the same player he had been, and even ignoring the one game at tackle he had given up more pressures than since early in his career, and he gave up a couple sacks at guard for the first time in a couple years. Did they see a continued deterioration?

Odd, to say the least.
