and Doug Mientkiewicz were among the offensive standouts
Are you sure you're talking about Doug "I can't hit my weight in the Majors" Mientkiewicz?
That's the guy. I remember watching him as a Double A star in the Twins' system, and he was projected to be the next Will Clark. He could tear it up in the minors, but never materialized.
Likewise, Wilkerson, who had some productive major league seasons, never reached the level that some expected.
