I'll take the Raiders. I really don't need anymore teams but I am in several "dead" leagues, and I can drop a couple of those. I find a league with little to no interaction rather boring no matter how good my team is. I also prefer leagues with at least 24 human owners and some of my current leagues have less.
Cincinnati Bengals: Been a fan since I started watching at 12 (1990-1991). Yes, that's the year that Boomer Esiason and Ickey Woods led them to the Super Bowl and lost to the Joe "Cool" Montana and Jerry Rice. I have never rooted for any other team. Even through the Dave Shula years.
How can I have three you ask? My dad was a coach, so I grew up loving not just my hometown team (KC), but good football in general. That led me to loving NE and GB since the mid-90s. Holmgren, Parcells, and Belichick are some of my favorite coaches ever (coach's son watches coaches more than teams ;)). My MFN game is actually modeled off of all three of them.
If I can convince Infinity to join, I'll take the Pats so he can have the Chiefs. Y'all just have to put up with all of my posts ending with #patriotsway or #bledsoewasbetter.
