Using old equipment following a rebrand is not uncommon. We usually see it during the OTAs and minicamps. But by training camp, most of the old stuff are replaced and the new gear are issued.
But this tweet from today that Jeremy Mincey is using his old helmet from last year. Not sure why. Maybe the current helmet is getting some repair.
Regardless. it’s an odd sight to see the old logo and helmet float around still at training camp following the team’s major rebrand.
