J.J. McCarthy shows progress in Vikings-Patriots joint practice

There's a lot to be gleaned from the Minnesota Vikings' final day of joint practice with the New England Patriots.

J.J. McCarthy, in likely his last reps against another team until the regular season, looked good in the 11-on-11 portion. McCarthy had a long stretch of passes without an incompletion. The play of the day was a long, 57-yard touchdown pass to Aaron Jones.

"It was nice to hit Aaron down the field. There was a little pocket movement before that," McCarthy said after practice. "I felt like the ball placement was there. A lot more accurate today than yesterday. But still a lot of throws that I want back and could put in better spots."

McCarthy was significantly better on Thursday…
