Better, yes. Very good? No. Sorry, but no.
Tackling needs huge improvement. Not getting any kind of consistent pressure on the qb. Still dreadfully slow in the backfield. Can't seal the edge. McCullers consistently underachieves, injuries and Couch being out are really hurting us as well.
Having said all of that, it is clear they are dramatically improved over last year. They're playing the whole game-not quitting at all. Don't take this post the wrong way, really not trying to be negative, but these major problems do exist and need to be addressed before we can say our D is in "very good" condition.
