One important issue to remember, is that this report only sheds light on the use of performance enhancing drugs (PED's) in baseball over the last 20 years. Even so, the report is still rather damning towards the Yankees. Over 15 former and current Yankees were named, including Kevin Brown, Jose Canseco, Roger Clemens, Jason Giambi, Jason Grimsley, Glenallen Hill, David Justice, Chuck Knoblauch, Josias Manzanillo, Hal Morris, Denny Neagle, Andy Pettitte, Gary Sheffield, Mike Stanton, Ron Villone, Rondell White, and Todd Williams.
Many of those players played key roles in the Yankees dynasty years of last decade. Roger Clemens pitched well with the Yankees during the 1999 and 2000 playoffs, winning two World Series games and a game against the Red Sox in the 1999 ALCS. Clemens is the only Yankees player listed, who is accused of using steroids throughout his entire tenure with the Yankees.
David Justice was traded to the Yankees in June of 2000. He then hit .305/.391/.585 with 20 home runs and 60 RBI in 78 games with the Yankees, to help them win the division over the Red Sox by 2.5 games. Later, Justice would go on to be the 2000 ALCS MVP with the Yankees.
Pettitte was with the Yankees in all four of their dynasty World Series years. He spent most of that time as the Yankees Game 2 starter and was a solid force in the playoffs. Although the Mitchell Report doesn't trace his use of PED's back any further than 2002, he may have been using them earlier.
Chuck Knoblauch hit .375/.500/.563 in the 1998 World Series. He also hit .333/.429/.389 against the Red Sox in the 1999 ALCS, and .313/.353/.563 in that year's World Series. His use of PED's was traced back as early as 2001, although he may have been using them earlier.
The Yankees also got considerable help from PED's when they played the Red Sox in the 2003 ALCS. Both Roger Clemens and Andy Pettitte received wins in the series with Jason Giambi hitting two home runs in the deciding Game 7, which went to extra innings. Mitchell claims that all three players had already taken PED's prior to that year.
