Peyton Manning is settling in and training camp is getting underway!  But now comes word that the Bronco's are shopping around for Quarterbacks...Hmmm?The Bronco's are bringing in quarterback draft prospects Kirk Cousins of Michigan State and San Diego State's Ryan Lindley for visits this week.  The Bronco's also flew down to Arizona State last week to give a private workout of Brock Osweiler.  The NFL Draft begins with the 1st round on Thursday, April 26th.  Makes me wonder if the Bronco's are worried about Peyton not being ready for the challenge of the upcoming season?  Tell us what you think?
