People get what happened with Richards wrong.
It is extremely likely he did in fact have serious immigration issues that take 6 months to correct at minimum. That meant he would have missed all of training camp and the first 3 months of the season.

Immigration issues fits the facts, how US immigration law is written, interpreted and enforced. It fits the timeline, Bill Daly's comments, and the leaks out of the Capitals.

"Under U.S. law, the mere admission of illegal drug use — in Ford’s case, an admission broadcast far and wide on American television — is grounds for a Canadian to be turned away at a crossing. The absence of criminal charges, let alone a conviction, doesn’t matter."

When pressed to clarify, Milne highlighted the words “admits having committed” and “inadmissible” in bright yellow. Translation: the admission of crack use is itself grounds for refusing a foreigner entry."
