Here are my takeaways from Day 1 of joint practice in Philadelphia, which was hot, physical, and saw both teams playing extremely hard.

Vikings defensive coordinator Brian Flores brought the heat at practice, challenging rookie offensive linemen Will Campbell and Jared Wilson.

The Vikings and Patriots just held their first of two joint training camp practices on a beautiful afternoon at TCO Performance Center. Fans packed the stands to watch as the Vikings got an opportunity to test themselves against a different opponent in a practice setting after weeks of battling each other.
