The 2007 Prospects set was one of the three main insert sets in 2007 Bowman. The cards feature players who Topps' team of scouts considered notable but were not yet major league players. Many of the players included are questionable at best. Players like Vincent Blue (who would be out of baseball before 2008) and several other players were included while more viable prospects were held back for the Chrome set that would be released later that year.
