I would assume that Assassin wasn't involved hands-on with the finished All Eyez on Me product. Even though not everyone was paid, as far as I know the proper people were credited for production, engineering, mixing, etc. in the booklet. (Feel free to correct me if I'm not entirely accurate.) Besides, in the interview where Suge was talking about that (in late 1996 after Pac died), he said, "Daz and all them other little producers and Assassin and all the ones we have, they did the tracks. Dre didn't do the tracks." (This can be seen in on the Welcome to Death Row DVD on the track entitled "Exodus.")
Personally I think Daz is equal parts e-thug and bullshitter. Back when Ruthless and Death Row were beefing, Eazy-E (along with Layzie Bone and MC Eiht) was on Ruthless Radio talking about the situation but some Death Row affiliates (Daz, Kurupt, Michel'le, D.O.C.) called in. Daz was being retarded, telling Eazy "You come talk to me when you sell a million records... I sold more records than you ever sold," or something along those lines (yet it was before Dogg Food dropped, which was Daz's debut with Kurupt), yet he failed to realize Eazy-E's involvement in the multi-platinum N.W.A. albums as well as his own platinum solo albums. Eazy cleverly replied with, "I bet you ain't seen a million dollars, you don't even make 25 cents a record." Then he started calling Daz and Kurupt out, telling them to come to the radio station and be on the radio rather than be on the phone. MC Eiht said a few things that were pretty neutral, but then Layzie Bone got on and was dissing Daz for talking big and dissing Ruthless as a whole on "What Would U Do" yet he had never seen any of them in person.
As far as being a bullshitter, let's not forget Daz's own lies:
* Daz once said on his website that he was enlisting in the army after the 9-11 attacks.
* Daz also said on his website that Suge and Death Row affiliates had kidnapped Kurupt and taken him to New York. (A few days later, it was announced that Kurupt re-signed with Death Row.)
* Daz said in an interview (before Still I Rise came out) that there were 700 unreleased Death Row tracks, many of which included Tupac (even though sources claimed there were 150+ unreleased at the time).
* Daz had taken orders for the Makaveli & Dillinger album, but he never released it, and from what I remember people were not refunded their money. The album was being sold for $50 since it was going to be pressed in limited numbers, but he was also selling a special edition for $500 that was autographed and included a DPG Recordz varsity jacket (probably identical to the one that Kurupt wears in his G-TV DVD).
* And the list goes on...
