If Rondell White is healthy, he is a less risky/more proven option than Luke Scott(a major gamble) at this time. And I don't understand why you don't get that we are discussing a healthy White acquisition. Why do you think Purpura said the team needs to examine his medical issues further? The organization isn't stupid and neither are the people on this board.
Btw, here are White's last few offensive seasons:
2005: 374 AB's, .313 BA, .348 OBP, .489 SLG
2004: 448 AB'S, .270 BA, .337 OBP, .453 SLG
2003: 488 AB's, .289 BA, .341 OBP, .488 SLG
Those OPS's come out to .847, .790, and .829. And he played in SD and DET for all but 22 games of those 3 seasons(ie pitchers parks).
In fact if I go back further:
2001: 323 AB's, .307 BA, .371 OBP, .529 SLG
2000: 357 AB's, .311 BA, .374 OBP, .493 SLG
1999: 539 AB's, .312 BA, .359 OBP, .505 SL
Those OPS's are .900, .867, and .863. The only bad year the guy has had offensively in the last 7 years was 2002 with the Yankees, where he hit .240, .278, .388=.666 OPS(and that is about the same kind of number that chris burke put up last year)
The bottom line is if White is healthy and considering his probable contract demand being in the 1-3 million dollar range he makes a very solid pickup for the organization, and provides them with a lot of lineup flexibility.
