I just finished reading Will's post on what poet each of the Royals would be, and, due to my accounting background and lack of any culture, I was able to recognize only 2 or 3 names. Therefore, I think that there should be a companion article for the less cultured (or Missouri graduates) comparing our Royals to Marvel superheroes.
Jason Kendall - old and revered for his durability. Lack of one overriding characteristic except "grit" and leadership. Captain America is most likely fit as the Cap has been around since the 1940s and has been the leader of the Avengers, etc.
Billy Butler - gap power, therefore not the strongest one there is (i.e. Hulk). Not exactly fleet of foot or good defensively (i.e. one dimensional). The Thing from the Fantastic Four is my pick.
Yuni Betancourt - lack of any skill that makes him useful to a team. Kitty Pryde (Shadowcat) of the X-Man whose main ability is to phase herself through walls or Nightcrawler of the X-Men whose ability is to teleport, however, leaves anyone he teleports sick and leaves behind a stench. Goi with Nightcrawler.
Scotty Pods - one dimensional, speed, speed, speed. No power. Quicksilver of the Avengers.
David DeJesus - does everything well, but nothing great, and always brings a smile to the ballpark. Can surprise you like this year. Go with Spiderman as has the strength of a spider (are spiders strong?), agility, and personality.
Zack Grienke - numerous weapons, but underapreciated until breakout season. Iron Man of the Avengers prior to the movie coming out.
Brian Bannister - intellectual with average ability. Mr. Fantastic of the Fantastic Four. Arch enemy would be Blade, the Vampire Hunter, who only works at night.
Joakim Soria - best at what he does. Definitely Wolverine of the X-Man who has killer instinct. Wolverine also has a healing factor and Soria seems to have the same with his ability to make the game exciting lately by putting runners on and then getting out of the jam.
Jose Guillen - supposed "leader" and veteran who most players (and fans) think is an asshole and too full of himself. Go with Cyclops of the X-Men.
For the follow up article, I'll compare the Royals to American beer. Yuni will be Old Milwaukee Light.
