The year that Rollins won Pujols, Wright, Utley and Chipper Jones all hit .320+/.410+/.545+. There were absolutely other options.
As for why a guy like Phillips isn't in the MVP race in the minds of plenty of people is this: RBI is not something that is a pure product of the player accruing them. Average, on-base percentage, slugging, defense, base running.... those things are completely dependent on the player at hand. Phillips is elite at one of those things and solid at the rest of them.
