With the No. 147 overall pick in the 2009 NFL Draft, the Buffalo Bills have selected Oklahoma LB Nic Harris.
Though he played safety in his time as a Sooner, the 6'3", 230-pound Harris lacks the straight line speed (4.65 seconds in the 40) and fluid hips to remain at the position in the pros. He does, however, have the size and upside to play outside linebacker in a Cover 2 scheme - which as you're well aware, the Bills employ.
Harris was a very productive collegian, amassing 232 career stops, 7 interceptions and 21 pass breakups from Oklahoma's defensive backfield. As it stands now, Harris will look to come in and compete with veteran Keith Ellison for the starting SAM linebacker position. There is a chance, however, that the Bills could bring in a vet to man the position; either way, this is a solid pick, as Harris is an excellent athlete and has some upside, particularly in this defensive scheme.
Buffalo's next pick is in the sixth round, No. 183 overall. Stay tuned!
