ENGLEWOOD, Colo. -- The burning question for the Denver Broncos this offseason, buried in the frenzy of Peyton Manning’s arrival and Tim Tebow’s departure, was the middle of the team's defensive line.

It was a mess, particularly after the underrated Brodrick Bunkley signed with the New Orleans Saints.

The Broncos, however, have quietly improved the defensive tackle position and it looks far from being an ugly situation. Now, I’m not saying Denver will have the best group of defensive tackles in the league. But after watching the unit at Tuesday’s minicamp, I don't think it is a lost cause either.

The team drafted Derek Wolfe (who can also play end) with the No. 36 pick and signed Justin Bannan. They agreed to a reduced contract with Ty Warren and are getting a healthy Kevin Vickerson back.

The Broncos are also giving former practice squader Sealver Siliga a chance at nose tackle. He is a wide body who is worth developing.

I see this as a group that will rotate often and be effective under John Fox and Jack Del Rio. Again, they may not be world beaters, but Denver’s situation at defensive tackle may not be as dire as previously considered.
