tom shady not cooperating with the investigation and not being honest did him in.
edit
goddell does not like being lied to. because when people lie and the truth gets revealed, like it always does, it causes people to doubt the integrity of him as a commissioner and the integrity of the nfl.
sean payton lied and felt the wrath. ray rice lied imo. i think he told goddell it was just a mild altercation and goddell believed him on gp and suspended him two games. once he found out the severity of the situation, ray rice felt the wrath.
psycho tom knows damn well he violated league policy and had he been honest and said yeah i like my balls a lil flat, no homo, and i paid dudes to ensure this. i apologize blah blah blah. had he done that then he would got off lite imo. but the smug cleft chin bastard just had to lie and be uncooperative. now he is being compared to lance armstrong of all people.
