There was a lot of good and a certain amount of bad for the Jaguars defense in Sunday's 24-17 victory over the Denver Broncos. After reviewing the game on tape, I'm going to give some analysis.
* The Jaguars held the second-ranked offense in the league to just 17 points and 323 yards of total offense. The 192 yard passing effort was Jay Cutler's lowest of the season, as was his 77.8 quarterback rating.
* Brian Williams at cornerback. The defense is simply better with Williams at corner, rather than at safety. Williams missed a few tackles and gave up some plays, but he's considerably better than Drayton Florence.
* The Jaguars defense made some plays. They forced three turnovers, although one of them really wasn't that forced (Marshall's fumble).
* Smith and Durant were back. Daryl Smith played his second consecutive game at a very high level, and Justin Durant was all over the field making plays.
* Reggie Hayward was very active, as he forced a fumble and batted down a pass at the line of scrimmage.
* Mike Peterson. He was bad when I watched the game live, and he was even more horrible watching it again. Peterson simply can't make plays anymore and he's almost always out of position as he takes terrible angles. With a bye week coming up, the Jaguars need to make the switch and put him on the bench. As poorly as Peterson is playing, I would take my chances with Brian Iwuh or Thomas Williams, rather than have the "captain" out on the field missing more tackles.
* Third down efficiency. The Jaguars allowed Denver to go 6/13 on third down and although the defense played well, they need to get off the field more on third down as they're ranked 32nd in the league in that statistic.
* Tackling. The Jaguars just aren't a good tackling team. The tackling was better than in some previous games, but make no mistake about it, they need to put people on the ground better.
