ENGLEWOOD, Colo. (AP) -- He's a big, raw Denver Broncos
quarterback with throwing issues who worked with UCLA offensive
coordinator Noel Mazzone on his own time to fix flaws.

Sound familiar?

While Tim Tebow's messy mechanics needed tons of work, Brock
Osweiler needs more tweaks than anything, and he worked this
offseason with Mazzone, who was his offensive coordinator at
Arizona State and also served as Tebow's throwing coach.

The Broncos' second-round draft pick took the field at Dove
Valley for the first time Friday, participating in the team's
three-day rookie minicamp.

Although his right elbow at times dropped below his shoulder and
winged out a bit, the 6-foot-8 quarterback showed he's making
plenty of progress in capitalizing on his superior size.
