Phorgotten Phillie Phile - Jeff Jackson

You can be phorgiven if you don't remember Jeff Jackson since, despite being the Phillies #1 draft pick (4th overall pick) in 1989, he didn't play a single game in the majors. This is probably his first card, a 1990 Bowman.He also appeared in the 1991 Bowman set, in a photo that looks remarkably like it was taken at the same time as the 1990 Bowman card.
Although he never played at the major league level, he does hold two distinctions. One, he is one of the 6 players picked ahead of Frank Thomas in the 1989 draft. Can you name the other 5?
His other distinction is the player wearing the most garish shirt on a baseball card.

The other 5 were Ben McDonald (quite the hobby rage at the time), Tyler Houston (picked by the Braves but who ended up with the Phillies), Roger Salkied, Donald Harris and Paul Coleman (who also never played in the majors).
