Broncos: One big question

Did the Broncos improve enough on defense?

Yes, it’s all about Peyton Manning in Denver. If the quarterback is healthy, the Broncos should score a lot of points and be in position to win a lot of games.

But if the Broncos are going to be a true contender in the AFC, they must improve on defense. Denver made solid strides last season on defense -- it went from No. 32 to No. 20 in total defense. Still, improvements are needed heading into 2012.

The Broncos went into the draft with a hole in the defensive front. They added Cincinnati defensive tackle Derek Wolfe in the second round and Tennessee defensive end Malik Jackson. He is versatile, but he is expected to play at end. Both players are expected to step into the defensive line rotation.

The Broncos tried to improve all layers of the defense this offseason, and they are better. The pass-rushing duo of Von Miller and Elvis Dumervil gives Denver a tremendous advantage. It doesn’t need to be great on defense, but it has to be better.

The draft picks of Wolfe and Jackson should help.
