The typical small cornerback, Brandon Boykin is athletic but not overly physical. Boykin weighs in at just 5'9", 182 pounds, but he offers return-man value as well.
Boykin's size may limit him to covering the slot, but in today's NFL, that's not the worst thing ever.
National Football Post wrote about Boykin,
Exhibits some savvy to his game. Plays a lot in the slot, loves to read the quarterbacks eyes and use his athleticism to make plays on the football. Is raw with his footwork off the line, consistently jumps backwards and/or shuffle steps into his drop. Is a better athlete than corner at this stage. Has the ability to sit into his stance and keep his base down, however, lets his pad level rise the further down the field he goes, getting sloppy and losing his technique.
Boykin is capable of playing in zone or man coverage, which helps his versatility.
Because his size is his only major limitation, Boykin will probably be able to contribute in his first pro season. He could see the field as a return man, as well.
Joining the Eagles in the wake of Brian Dawkins' retirement, Boykin fills a gaping hole in the Philly secondary, so he'll likely get every opportunity to be an impact player.
