They're alright. They could certainly worse even if they are a bit generic.

The Guardians logo having red teeth is off-putting. I like the Dragons logo, but it does look quite a bit similar to UAB.

I actually am very pleasantly surprised by the quality of these logos (of course, I DID expect total garbage, so it's not like the bar was set high)...

Dallas Renegades: Logo's okay, doesn't really stink, but isn't special either.  I'm going by the wording to predict the color schemes here, so I could be wrong, but with Dallas being in light blue and Renegades being in black, I predict a light blue/black combo, which could be potentially very nice (if the main color is light blue). 

Houston Roughnecks: Not feeling the Roughnecks name, but the logo is fine.  I do like how they totally stole the Houston Oiler's oil derrick and then just stuck a H in front of it.  Pretty bold move.  That being said, going by the colors of the team name, of COURSE we get a navy/red team  (not like there's a million other teams with that color combo already .....which would be similar to the Houston Texans.   Predicting their main color to be red to avoid looking too alike.

LA Wildcats: Generic logo, but the letters are stylized nicely.  Out of all the possible ways to put out a "LA" logo, this is one of the better designs they could have went with.  I actually like it.  I REALLY love the red/orange color scheme.  Definitely gives me a Tampa Bay Buccaneers cream-sickle feel to it, and I did love that jersey!  Main color should be orange for sure!

New York Guardians:  I think this is the best one.  While the red teeth is a strange, morbid, idea, I love the gargoyle motive they're presenting.  It's dark, intimidating, perfect for a gothic New York theme, especially with the black, silver, and red color combination.  Black likely being the primary color for this one.  Might be my favorite team for all these reasons.

St. Louis BattleHawks:  Not sure why Hawks wasn't good enough for this team, but BattleHawks isn't the worst team name ever.  Too bad their logo isn't effective.   While it's nice, I feel it belongs more in a Legend of Zelda game then it does a professional football team.  I'm guessing a blue and silver color combo.

Seattle Dragons: It's already been said, but yeah, this logo totally ripped off UAB... and it's an inferior rip off too.   I love the name Dragons for a team, but I'm not sold on the logo.  Going by the lettering, we would actually get a Navy/Orange combo... not what I'd guess but it would be different and I like navy/orange team combos.

Tampa Bay Vipers:  While the logo looks cooler with a black background (looks a bit like a snake eye), it's still just a V... Nothing more to report.  Green and yellow is a great color combination though, so I look forward to seeing the jerseys!

DC Defenders:  Very boring and doesn't look at all like a football team. Red and white makes sense for a color combination and it's not the obvious red, white, and blue scheme.  Still, pretty lackluster.
