I have been thinking for a while that it is strange that Wilf isn't getting more heat for his conviction this year and if he loses his appeal, do you think the league will do anything to sanction him in any way? To me it cannot be a good PR move for the league to have an owner who was convicted for racketeering and they may want to have him step down.

If you remember, Eddie DeBartolo Jr. had some legal problems:

DeBartolo was involved in the corruption case of former LouisianagovernorEdwin Edwards. DeBartolo pleaded guilty to a charge of failing to report a felony, and received a $1 million fine and two years of probation in return for his testimony against Edwards.[7] Edwards was on trial for extortion and other charges, among which were the $400,000 he demanded from DeBartolo to gain a river boat casino license.[7] DeBartolo never received the license, was fined by the NFL, and barred from active control of the 49ers for one year.[8]
That legal battle led to another, and as part of a settlement, DeBartolo gave up control of the 49ers in 2000, ceding control of the team to his sister Marie Denise DeBartolo York. York had previously been the president of the DeBartolo family-owned Pittsburgh Penguins. In 1991 he arranged to sell the NHL franchise to assist the DeBartolo Corporation in the aftermath of the real estate collapse of 1987. Many shopping malls were sold to theSimon Property Group in 1996, which operated for a few years as the Simon DeBartolo Group.

I can see some similarities in the two situations and in the end Wilf has a lot less clout that E.D ever had. It seems his conduct, even though it happened prior to his purchase of the team, could be detrimental to the league. Possibly as detrimental as his ownership has been to the W/L record of the team.
