They seem kinda average at coverage to me. I recall a couple of things... We were poor in pass defense, and we set a Miami Dolphins record for fewest takeaways ever. Not good.
I vividly remember two sure-fire INT's of Andrew Luck dropped by Smith (CB) and Dansby (LB), that were harder to drop than catch. Either INT would have won us the game most likely. Dansby dropped a pick six. He gets credit for being in the right position, but that is the sort of play high paid impact LB's are supposed to make. He rarely produces turnovers, ditto for Burnett and Misi. At a minimum I'd say our LB corps needs to show major improvement in the takeaways department. I'll give them an average grade, but I can't see how they deserve to be considered exceptional at coverage.
