Three and out: Nick Underhill’s thoughts on P.J. Williams, Craig Robertson and Garrett Grayson after the first day of Saints minicamp _lowres

1. WILLIAMS SHINING

It was a strong day for Saints cornerback P.J. Williams. He had a one-handed interception on a pass that ultimately carried him out of bounds, jumped a route in team drills intended for Brandin Cooks and dropped an interception, and also broke up a pass. He’s playing both on the outside and in the slot. Getting him up to speed will be a big development for the defense and give the Saints another solid corner.

2. COME ON, CRAIG

Linebacker Craig Robertson was another player who looked good. He has solid speed and has the ability to flip his hips and run with receivers. I saw him break up a pair of passes and flash a few other times. His athleticism is notable considering how the second group of linebackers looked last season behind Dannell Ellerbe. Having his coverage skills should help this group.

3. GRAYSON UPDATE

There were things quarterback Garrett Grayson could have done better — and a few passes that he would have liked to have back, including one that should have been intercepted — but he had one impressive moment during team drills. After surveying the defense, he checked out of the initial play and hit his running back on a quick screen for a huge gain. It was the perfect call against the defense. It’s a small thing, but it’s progress.
