The most obvious area in which Wallace is better than Holmes is the reason that Santonio Holmes is no longer a Pittsburgh Steeler: discipline issues. No one has ever questioned Holmes' performance on the field. He has a knack for coming through in clutch situations. However, his behavior away from the field leaves a lot to be desired at times.
May 27, 2006- Holmes was arrested in Miami Beach, FL for disorderly conduct. Holmes paid a fine and the charges were dropped.
June 18, 2006- Holmes was arrested again, this time for domestic violence and assault in Columbus, OH. The charges were later dropped.
October 23, 2008- Holmes was arrested in Pittsburgh, PA for possession of marijuana. The Steelers deactivated him for a game as a result of this arrest.
March 24, 2010- Anshonae Mills filed a lawsuit against Holmes over an incident on March 7, 2010 in which she claims that Holmes threw a glass at her in an Orlando, FL nightclub, cutting her above her eye. This was the incident that ultimately led to Holmes being traded to the New York Jets.
April 29, 2010- According to authorities at Pittsburgh International Airport, a flight attendant told police that Holmes wouldn't turn off his iPod when requested and asked that officers speak to him. Officers spoke with Homes, but no charges were filed.
Holmes has also made questionable comments on his twitter account. He told one follower to "kill urself", and made marijuana references in another tweet. To this point in his career, Mike Wallace has not had any of the off-field problems that Holmes had.
