yes. the team has numbers in summer camp.
I am very high on Gonzo and believe Jon Jones if healthy is a border line pro bowl player. Marcus imo is too small to play the majority of the snaps at the 3rd CB spot.
the team lost Jackson, Bryant and Mills from last seasons team. Jack Jones too. when everyone was healthy and available, Wade was behind all of them. Austin showed some promise, but he was a street free agent the entire season.
another veteran is needed
The Patriots currently list Marcus Jones as slightly bigger than
"border line pro bowl player" Jon Jones (188-185), so I'm not sure why you keep saying he's too small. He's not too small to cover Tyreek Hill and Jaylen Waddle... he's just right.
JC Jackson wasn't playing particularly well when he was here, he wasn't the same confident player he was when he left... so he's not a huge loss.
Also not sure where you're getting your Shaun Wade take from, he played a lot in the first month, he started six games on the season. He hurt his shoulder midseason and missed some time, missed one game in week 11 to covid... but when he came back healthy he played quite a bit and played really well to end the season. Last season was the first season I can remember him playing at all and first I remember saying something positive about Wade. They played him all over as well, some free safety included. He was good, it surprised me as I had written him off.
I won't slam Myles Bryant on the way out the door, let's just say I wish him well elsewhere and always have.
Jack Jones sucked terribly, beyond the airplane and guns he got toasted on the field. Crappy play and a loud mouth will get you booted out the door... good riddance. He's someone else's problem now.
Mills is the only person who might be missed, I also think they can replace him with another CB at FS.
The player you're forgetting or omitting is the second most athletically gifted CB on the team after Gonzo. Marco Wilson is a ridiculous athlete and has been starting the last three years for a dog in Arizona. They didn't acquire him until two weeks left in the season so we barely saw him. I expect him to start opposite Gonzo or somewhere this season. He is finally on a great defense and should be able to show his worth. He is better than any single DB they lost.
Marcus Dial is a fast tall strong border CB who uses the sideline extremely well based off college tape. He doesn't have ridiculous agility, but it didn't seem to bother him at South Carolina. He ranked #3 in passes defensed two years in a row in the SEC, he played a lot of football and started a lot of games.
Two players who provide some potential excitement is Isaiah Bolden, and the other is UDFA from this offseason Azizi Hearn. Both of these guys are roughly 210 pounds, they're big. Bolden has pure speed and was a dynamic kick returner in college. He even looked pretty decent at CB until he went down with injury.
Hearn had very good measurables across the board, he was big at 6'1" 206 pounds, he had very good speed (4.48 forty), strong (18 reps), explosive (37.5" vert/127" broad) and his agility was exceptional for a guy his size with a 4.23 shuttle and 6.92 cone. He had a long circuitous route through college but settled at UCLA and defended a lot of passes last season. His best football might be ahead of him.
Even guys like Alex Austin and Kaleb Ford Dement has some tools to work with.
In short, they lost some more experienced veteran guys, got a lot younger but they also let a lot of really ordinary players walk and got a lot more athletic. I don't see the big need... here's my projected depth chart with all the garbage removed:
FS – Shaun Wade, Marcellas Dial,
BIG CB – Christian Gonzalez, Marco Wilson, Isaiah Bolden, Azizi Hearn,
Alex Austin (PS),
SLOT CB – Jonathan Jones, Marcus Jones,
Kaleb Ford-Dement (PS),
That's a great mix of talent and some vets mixed in, better than last year's depth chart. The defensive front just has to do their job.
