Colorado's depth chart is much different than it was after spring practices, starting with an official switch to a 3-4 defense and true freshman Greg Henderson earning the starting nod at right cornerback opposite senior Travis Sandersfeld.
Henderson and Sandersfeld have the biggest challenge for the Buffaloes, as they are replacing NFL draft picks Jimmy Smith and Jalil Brown.
As for the 3-4, Josh Hartigan switches from a defensive end to "Jack" outside linebacker. Will Pericak moves outside from tackle to end, while Conrad Obi is officially a nose tackle. The Buffaloes ran a 3-3-5 last season.
Here's the word on the defensive scheme from the official website.
The coaches are now listing the base defense as a 3-4, instead of a 4-3 which has been in place at CU since 1995; the Buffs last lined up in the formation in Bill McCartney’s final year as head coach in ’94. A newly-titled position, “jack” outside linebacker, now complements the two inside linebacker spots (“mike” and “will”) and the opposite outside one (“sam”). Josh Hartigan is the jack OLB, with the former defensive tackle now becoming left defensive end and is manned by Will Pericak and Curtis Cunningham. Conrad Obi (nose tackle) and Chidera Uzo-Diribe (right DE) are slotted next to the left end.
Sophomore Derrick Webb is the starter at the "Will" inside linebacker spot ahead of senior Patrick Mahnke.
Also on defense: True freshman Kyle Washington is the backup strong safety behind Anthony Perkins.
On offense, there aren't any real surprises, other than there being an "and" between senior receiver Tony Clemons and true freshman Tyler McCulloch, meaning they are considered co-starters at the "X" receiver.
There's also an "and" between redshirt freshman Daniel Munyer and sophomore Gus Handler at center.
Finally, the Buffaloes announced their team captains: quarterback Tyler Hansen, guard Ryan Miller, linebacker Jon Major and strong safety Anthony Perkins.
