I'm hoping it's cuz Byrd was nursing his groin, but it looked, at least in the 2nd half, that the 2 primary safeties were Wilson & Whitner, w/ Byrd only coming in when extra DBs were required. IMO, whitner is better defending the run than Byrd, but Byrd is SOOOOO much more likely to generate a big play in the passing game, I don't see how you can field Whitner over Byrd unless you KNOW they're gonna run, or if Byrd is injured. And Wilson is better than Whitner in both aspects, so should also be starting ahead of him.
