UPDATE: The Broncos have added some beef to their backfield, adding Auburn running back Mario Fannin and Miami fullback Patrick Hill.
Hill is an absolute bowling ball at the fullback position at 5'8" 237 pounds, and he only ran a 5.09 40 at the Miami pro day, but he won't be expected to tote the rock all that much. His role with the Broncos will be to plow people out of the way to make room for guys like the next signing, Mario Fannin.
Fannin was not productive at Auburn, which is somewhat of a red flag to me except for the fact that Auburn's backfield was extremely crowded a year ago. Splitting carries with an extremely talented freshman back in Michael Dyer, as well as Cam Newton taking a lot of the rushing load limited Fannin statistically, but his measurables are insane.
Fannin is 5'10" 237 pounds, and he ran a 4.37 at the NFL scouting combine, which is an astounding number for a man the same size roughly as Shonn Greene, who ran in the 4.6 range.
The NFL's undrafted free agent signing period is underway, and as you would expect after a long, long lockout, fans are just starved for real NFL information.
The Broncos are off to a quick start as well, signing Rutgers cornerback Brandon Bing already, and now reportedly adding a pair of wide receivers in Wake Forest's Marshall Williams and Michigan State's Mark Dell.
Williams is a 6'1" 190 pound receiver who ran a 4.62 40 yard dash at his pro day, so he's not overly fast, but he was 2nd team All ACC in 2009, but had only 24 receptions a year ago.
Mark Dell had a career year for the Spartans last year, catching 51 passes and six touchdowns. He measures out at 6'0" 193 pounds and he has the ability also to return kicks. He ran a 4.54 40 at the Michigan State pro day.
