Denver Broncos Waive OL Tyler Polumbus, Assigned TE Kory Sperry from Miami

The Denver Broncos have placed offensive tackle Tyler Polumbus on waivers.  Polumbus was signed by the team as an undrafted free agent in 2008, and started eight games in 2009 in place of Ryan Harris.

Polumbus did not transition well to the Broncos' new power blocking scheme, and was replaced on the depth chart by D'Anthony Batiste this pre-season. 

Sperry is a second year veteran from Colorado State who played in eight games for the Dolphins last year.  He had three catches for 31 yards and a touchdown.

He was originally signed by the San Diego Chargers as an undrafted free agent.

Sperry stands at 6-foot-5, 238 pounds, and is a Colorado native. 

Here is his scouting report from the 2009 Combine:

A three-time Mountain West Conference honoree, Sperry presents teams with an intriguing blend of size, straight-line speed and soft hands. Few tight ends across the country can match his production, as Sperry leaves the Rams with 141 career receptions for 1,763 yards and 20 touchdowns. Despite his physical tools and eye-popping production, Sperry could struggle acclimating to the NFL. More of an H-back than a traditional tight end capable of blocking out of the three-point stance, Sperry's chances of being anything more than a late-round gamble depends on the trend of NFL offensive coordinators looking for players who present athletic mismatches. Had an arm span of 33 3/8 inches and a hand span of 9 1/2 inches at the combine.

Positives: Lanky, athletic build with room for additional muscle mass without a significant loss of quickness. Versatile athlete capable of lining up as a traditional tight end, H-back or even split out wide. Good initial burst to get off the snap. Gains a clean release off the line of scrimmage due to quick hands and agility. Good straight-line speed to challenge the seam. Natural receiver. Big, soft hands to make the secure catch. Rare body control for a player his size. Can contort in space to make the difficult grab. Can track the ball over either shoulder. Good quickness off the snap to get to the second level as a run blocker. Has the lateral agility to remain square to the defender in space.
Negatives: Only lined up in the traditional three-point stance half of the time and may struggle to make the transition to a more traditional pro-style offense. Inconsistent effort as a blocker, ducking his head too often in space and lacks the physical strength and technique to contribute much in this area. Relies on his athleticism, rather than sound route-running, to get open. Has to prove he's 100 percent recovered from the torn ACL that limited him to only two games in 2007.
