These are all the rumors why Al is furious but can't or won't say anything; and why Allen pretends to act confused as to why Al hates him.
Both know the truth and the hold out for more money is the cover story.
1) Marcus was sleeping with Al's neice;
2) Marcus was dating one of Als best friends daughters and the friend didn't like it and asked Al to have them end it. And Marcus told Al to frick off.
3) Marcus was frickin' a lot of the players' wives.
4) He was failing drug tests - Ricky Williams style.
5) He was boning OJ's wife.
6) He was giving Rozzell dirt on Davis.
7) He was gambling on football and picking against the Raiders; supported by Al claiming Marcus was faking injuries during games to come out of the lineup AND Al never forgave him for the fumble in the Eagles game when the Raiders were already in field goal range.
