Harry has stud potential heading into his second season and healthy. Edelman and Sanu, another sophomore in Meyers, FA signing of Lee, the leading candidates to Land Gordon (ok, that doesn't mean anything unless he's beaten his deamons), and drafting two big tight ends fairly early by Patriots standards (even moved up to get one), and I can honestly say I'm not worried. But I never worry, Belichick is the GOAT, I just enjoy the ride.
As for Cam, he's a low risk, inexpensive and high reward signing. If he wins the job and if he produces, he gets paid. Otherwise he's just a cheap insurance policy.
He'll also play by Belichick's rules, or he'll be gone.
PS: they're contenders. As always, I put my money where my mouth is
