More helmet concepts keep coming

Helmet concept designs by Paul Bunyan Design.

The offseason tradition of uniform speculation is in high gear right now. Last week we showed you these helmet concepts. Just this morning the Cleveland Brownsunveiled new logos. And now more unofficial helmet concepts have surfaced.

These designs are coming from Paul Bunyan Design. Just like the gallery last week, these helmets are impressive. Some of these designs could replace their current helmets immediately. The others, well, not so much.

The Chargers helmet plays with the team name a bit and is pretty sweet with the barrage of lightning bolts. The Cowboys helmet isn't nearly as drastic, but I like the matte finish and it would go well with the team's old school look.

Some I don't see happening at all. This Packers design is an homage to the cheesehead theme, but the toned-down green reminds me of moldy cheese.

Also, this Cardinals one is frightening. I'm not normally intimidated by such a small bird, or helmet logos for that matter, but look at those eyes just staring into your soul. It's a bit unsettling.

What do you think of this round of helmets? You can check out the full gallery here.
