Good decision. It's up to him if he can make it back or not. If the Commish reinstated him that quickly, someone will be willing to pick him up and give him a try.
Also, don't think for a second that the buzz generated by his return and the attention (Good or bad) given to the league wasn't taken into account. If he makes a team and plays, even preseason games will be hard sell outs just so fans can show up to boo him or just take in the specatcle.
