Gibson had a lot less competition, right? Hughes, Nolasco, Santana, Gibson are starting on the roster on day 1, unless there is an injury. That leaves 1 spot for a guy that is a veteran, or that had some good starts last year, or that has a history of good starts, or for a guy they limited to 80 pitches a start in AAA last year that finished the year hurt......ok, maybe I biased those descriptions, but maybe not.
