Patriots have become the team to beat over the last decade. They just can't help but win Superbowls. That's' why when they don't make it to a superbowl, it is generally more exciting because there is an earnest debate about who will win. Once the Patriots are involved, you might as well put your money on them. Their logo and helmet, however, is a little stiff. Some of these helmet designs really go bold with their direction.
The bottom left design is the biggest departure since it actually gets rid of the Patriot logo altogether, instead using harsh lines and big colors. The bottom right design seems like a good compromise between keeping the logo while still moving towards a big change. The top right is the one that misses the mark the most. It is too similar to a Dallas Cowboys style of design.
