I respectfully disagree, Ian.
A reporter doesn't show "discretion and restraint" via innuendo and veiled suggestions of behavioral or other issues.
If Reiss has verified knowledge about a player that is more than several years old and is relevant to a situation (in this case, a contract negotiation) and if he feels he must report it, he should report it.
If Reiss has that knowledge and has decided to protect the player by not publishing it, he should protect the player and not report it.
For a reporter with Reiss' credibility, suggesting that something might be wrong implies that he knows that something is wrong. He can't have it both ways.
Reiss now has two alternatives: publish the whole story, if there is a "whole story," or retract the "incomplete piece" that he wrote earlier.
