The Tampa Bay Buccaneers already have a pretty intense helmet design, especially compared to teams like the Greenbay Packers and the 49ers. I mean, a skull and crossbones hits a little harder than a G or a 49, no offense to either team. There is something visually striking about the menacing skull, although that also means it can come across as a little childish.
These new designs really lean into the skull design, making it even more prominent in some cases. The giant skull in the bottom right might be easy to see from the stands in a stadium, but that's a pretty big cartoon skull. The bottom right strikes a good balance between the cartoonish skull and a more refined design. Ultimately, I'm not sure the candle apple sheen of the top right design is the right look for a football team.
