Rookie receiver Greg Childs delivered the highlight reel play of the day in the final team session of this afternoon's Vikings practice. With the second unit offense and defense on the field, Childs' 26-yard touchdown catch from Joe Webb came on a play during which cornerback Brandon Burton had near-perfect coverage. Yet with the receiver and cornerback face-to-face in the end zone, Childs leaped, reached both arms around Burton and managed to pin the ball on the cornerback's back long enough to haul it in.

Said fellow receiver Jarius Wright, a friend of Childs' since childhood: "I've seen that since our school days. Greg making catches like that? There's nothing new for me to see."

Added head coach Leslie Frazier: "That was a nice play. We saw him do that in college as well. That was a real nice play. Great concentration. That's what we need. We need a guy to make that hard catch for us even when he's covered. That's good to see."

Thursday's defensive standout may well have been cornerback Chris Cook, who's clearly established himself as the team's top cornerback. Cook had two eye-opening interceptions this afternoon. The first came in 11-on-11 work on a throw up the right sideline made by Christian Ponder and intended for Percy Harvin. Cook made an athletic grab and raced the other way.

Later, with the defensive backs matching up against receivers in drill work, Cook made up ground on rookie Jarius Wright and made another nifty pick of a Sage Rosenfels pass.

Cook has been superb in camp so far, a good sign as he comes back from the off-the-field troubles that cost him the final 10 games of 2011.
