Details over the suspension are murky, and Miller continues to proclaim his innocence. Miller and the NFLPA initially said that the suspension is not for performance-enhancing drugs, which led to many pointing toward substance abuse as the culprit (Miller did test positive for marijuana and amphetamines as a rookie).
However, USA Today and the Denver Post recently reported that the suspension is not a result of a failed drug test. If there are no drugs involved, the suspension could simply be a matter of Miller having missed a test or drug-counseling session.
The Broncos can hardly afford to lose their dominant 24-year-old linebacker for any amount of time. After losing Elvis Dumervil during the offseason, Miller will be counted on even more to lead the team’s pass rush. We should find out more following the result of the scheduled appeal.
