The Patriots and Panthers wrapped up day one of two days of joint practices. Here are five things that got my attention.

1. Defense dominates: I thought the Patriots defense ruled the day. They looked good in group and team periods. The defensive line got consistent pressure on Baker Mayfield and Sam Darnold in team and they controlled the line of scrimmage against the run game.

The secondary did a good job in coverage specifically Jalen Mills, Marcus Jones, Shaun Wade, Kyle Dugger and Jonathan Jones. All five were routinely in phase in one on one situations and they made plays in contested catch situations.

2. Thornton puts on a show in 7 on 7: Thornton continues to build on what has been a terrific camp for him with a strong practice. He made a spectacular diving catch on a deep over corner route and followed that up with a great 10 yard out cut in 7 on 7. He carried over the strong play in team. He ran clean routes and was able to separate from both Jaycee Horn and C.J Henderson.

3. Mac was on point: I thought Mac Jones threw the ball well. He showed good timing, anticipation and zip on his throws in both skelly and team. He did have a couple of passes knocked down and he made a bad decision in two minute that resulted in a pick but overall, I thought he had a good day.

4. Judon teaches Ekwonu a lesson or two: Matt Judon versus Panthers rookie Ikem Ekwonu was one of my match ups to watch heading into these joint practices and it didn’t disappoint. Judon and the rookie matched up several times and while Judon got the best of the rookie on more than one occasion, I thought Ekwonu held held his own. It will be interesting to see how he adjusts tomorrow.

5. Belichick spends bulk of his time with the offense: Bill Belichick spent most of the practice with the offense. At one point after a situational team period, he pulled guard Arlington Hambright and center James Ferentz aside and worked with both. Belichick got on the offense about substitution errors and a lack of fundamentals during the various periods of practice.

Belichick has always been a hands on coach and we saw that today as he tries to help a struggling offense find consistency.

For what it is worth. I will not dwell on the fight. Camp fights are a way of life this time of year. It is not a big deal or worth talking about.
