Because 3 out of the last 5 have been named that way. Bland strength. Other than the Jaguars (relevant zoo animal at least), Panthers (literally named because panthers are strong), and Titans (...), you got the Ravens (famous resident and good) and the Texans (relevant...local...population?). To be fair to the Texans, they probably would have been the red/white/blue Oilers if they could, but damn.
Redtails is at least interesting, although also weird since they got the nickname due to the, you know, red tails on their planes. Reminds me of redasses when applied to people instead of planes. Redwolves and Warriors are not interesting, but hey Snyder could probably reuse alternate logos with those and keep selling dat merch. Instead of these types of things, I wish they'd come up with something relevant to their local area or at least fun. Like the Biscuits.
