One thing to know about Brandon Boykin during training camp this year : Dude's making an impression.

He's showing he is capable of playing both the inside nickel spot and the outside corner spot, it seems like everyday he is making plays regardless of where he is lining up.

"Yeah, I've seen Brandon show up," Eagles head coach Chip Kelly said about Boykin.  "I talked about it the other day.  Brandon has had a nice chance."

His first impression on the field this camp has been just strong, and while the fact the Eagles signed not one, but two cornerbacks this offseason didn't surprise just anyone, it would be shocking to many if Boykin won, one of the starting jobs.  However, after watching the way he has worked in training camp maybe the shock wouldn't be so great, since he is getting reps at both nickel and outside corner.

"He's getting both," Kelly said about where Boykin has been getting reps.  "I couldn't sit here and tell you exactly how many he's getting inside or outside.  I know he's playing both."

His speed and explosiveness was evident on Sunday, when he was making plays all over Lincoln Financial Field.

"Brandon is explosive," Kelly explained.  "I thought he played really, really well yesterday.  I haven't seen today's film, but yesterday he did a really nice job in the stadium.  He showed up, made a play again.  Whether it was in special teams or in the team in seven‑on‑seven situation.  I'm pleased with where he is so far."

With the departure of both starting corners from last season, so far this training camp Boykin has been given an opportunity to make his case for regular playing time both on the inside and outside.

"He's got the potential to play both," Kelly said.  "I think that's what we're ideally looking for.  We need to, in our mind, figure out exactly who the corners are."

That's a good question, who exactly are the corners?

After skipping all of OTAs, offseason pickup Cary Williams is missing time with a hamstring strain. Bradley Fletcher, also inked in the offseason has failed to distinguish himself.  Williams and Fletcher were signed in the offseason and presumed to be the starting pair on the outside, Jordan Poyer was a sleeper pick, taken in the seventh-round of the draft - nobody really thought much of Boykin.

"I think he's the one guy that we're using inside at nickel that can do some of those things. [Eddie] Whitley is another guy," Kelly stated.  "[Jordan] Poyer is the third that we're working through those positions."
