Brown was reportedly outstanding during voluntary workouts and minicamp. According to Graham, coaches raved behind the scenes about how well Brown has practiced.
Of course, looking good without pads on during the offseason will be much different than replacing an every-down dynamo with a cult-like following.
The 6-foot-1 Brown played inside linebacker at Louisville, but he is versatile enough that the Bills used him as a nickel linebacker in offseason practices.
NFL Media's Mike Mayock said during the draft that after watching Brown's tape, "I thought he could play three downs. He's a bit of a throwback type of player."
Plays are funneled to the weakside linebacker in new coordinator Jim Schwartz's defense, so if Brown wins the starting job he will be expected to become an immediate playmaker -- consider DeAndre Levy's role with the Detroit Lions last year as a template.
However, the Bills appear to be hoping that lightning will strike again with a rookie linebacker.
