The Denver Broncos had an eventful offseason.
They signed the best slot receiver in the NFL in Wes Welker. They signed the top guard on the free-agent market in Louis Vasquez. Dominique Rodgers-Cromartie was brought in to improve a defensive backfield that had the top cornerback duo in all of the NFL last year.
And that was just free agency.
The Broncos filled in key holes at defensive tackle, defensive end and running back by drafting such players as Sylvester Williams, Quanterus Smith and Montee Ball.
Denver was a 13-3 team last year that finished short of its Super Bowl goal in 2012.
Entering 2013, it is one of the top favorites of bringing the Lombardi Trophy home. Which of these offseason additions will likely have an impact, as opposed to the ones that won't?
