Okay, the names that do not seem to cause any conflict or confusion.
Orlando Pelicans
Orlando Raiders
Orlando Tigers
Orlando Dragons
Orlando Hornets
Orlando Wolverines
Orlando Mustangs
Orlando Rockets
Orlando Lions
It's somewhat in Orlando's hockey history to have a team name that stars with 'S'. Solar Bears, Seals, and Surge.
The deviants are the Rollergators, and Jackals. Both roller hockey teams coincidentally. Although the Surge were too.
Orlando Seagulls? There used to be the San Diego Gulls, who actually made their way into the ECHL at one point, but haven't played since 2006.
Names that might be okay:
Polar Bears
Black Bears
Barracudas (a fan favorite to call the team that became the Seals, but was used by Jacksonville (ACHL/WHA2/SPHL). Now defunct)
Lightning (barring affiliation; there WILL be people confused by this, however)
Spiders (rumored name change for the non-existent WHA revival. Don't care for it myself.)
Intensity
Jets (a personal favorite, but with Winnipeg back...)
Armada (possibly too close to Admirals, as it refers to a naval fleet)
Chargers (the connotation is with electricity, but the term stems from the middle ages for a warhorse)
Cobras (the urge to call the coach/gm/captain/or myself 'Cobra Commander' may be too great)
Pythons
Surge (too soon? Very few remember they ever existed, naming rights could be issuematic)
Names that seem to be out:
Thunder - Stockton (ECHL)
Seals - history
Jackals - Elmira (ECHL)
Sharks - multiple
Storm - Tampa Bay, Toledo (ECHL)
Gators - Florida (NCAA)
Ice Gators - Lousiana (SPHL), also stupid.
Pirates - Portland (AHL)
Grizzlies - Utah (ECHL)
Knights - UCF (NCAA)
Warriors - too similar to Greenville (ECHL)
Bears (simply) - Hershey (AHL)
Cougars - modern connotation
Shock/Shockers - modern slang
Riptide - sounds like 'Rip Torn'
Express (named for the high-speed rail line between TB and Orlando that I hate and think is going to be a disaster, as well as the SunRail system planned - may be confusing when/if these things do open) - Chicago Express (ECHL)
I think putting 'Thunder' before something makes it 2x as good. Thunder Bears, Thunder Pelicans, Thundercats, etc.
