Lane Johnson is getting used to seeing Derek Barnett throughout these Philadelphia Eagles voluntary OTA practice sessions.

Not only is Johnson lining up against Barnett on nearly every down, he's getting used to turning his head and seeing Barnett approaching the quarterback.

A lot.

"Toward the end of the team portion of practice, rookie first-round pick Derek Barnett really began to shine," wrote CSN Philly's Dave Zangaro. "On consecutive plays, he beat Lane Johnson, who has been playing left tackle.

"When the Eagles drafted Barnett, Joe Douglas raved about the draft pick's "ankle flexion." That was on display Thursday; when Barnett gets so low to the ground without losing speed, it's tough to get hands on him."

Instead of getting frustrated over the Eagles' first-round pick constantly beating him, Johnson has given Barnett plenty of accolades for his performance as voluntary OTAs come to a close.

Even in helmets and shorts, Barnett is showing flashes of his potential against one of the best tackles in football.

Playing opposite of Brandon Graham will only ease Barnett's transition to the NFL, which could equate to to high pressure numbers and sack totals in his rookie season.
