"Did you see it?" Antonio Brown">Antonio Brown asked with an ear-to-ear smile.

Brown confirmed what was seen in a Wednesday practice during 11-man work. I asked Brown how he scooped up a low pass toward the sideline with his left hand while in a full-out dive.

Brown said he couldn't remember if he used two or three fingers to grab the ball, but a full extension of five fingers wasn't possible because of the position of the ball. Brown showed the scooping motion with his hand to describe the catch.

This is the kind of catch you'd want to see on video footage, which is prohibited during team work.

Brown made a lot of difficult catches during training camp, which was open to the public, but this was his best.

As Todd Haley recently pointed out, Brown is 'trying to be the G.O.A.T. by building off his 239-catch performance from 2013-14. Catching Jerry Rice would take a while. By the looks of Brown the last month, he seems eager to maximize his potential.

It's no surprise to quarterback Ben Roethlisbeger that Brown made a dynamic play by the sideline. Roethlisberger told ESPN's Mike & Mike this week that Brown is "the best feet-on-the-sideline receiver I've seen in my life."
