Unsavories for both Dennis and French that I can think of:
French
1) Horrible one-sided contract. Obviously it was written to protect French. But, since French was paying for Flights, Motels, Entry Fees, Gambling Matches, Food, and even Clothes, in reality, French acted in good faith and wasn't scr_wing Dennis.
2) Allowed during the Ko/DO stream to let people think that he organized it. To me, very minor, since many of the accolades for the 100k match with Shane were mixed in.
3) Discussed signing the Ko brothers during the match with Dennis. Not good, but considering the fact that the Ko brothers had no money and needed to be backed by someone in order to get to DCC – again, understandable on French's side. Someone suggested that the signing was in the works for 6 months. Not from what French said. Backing Ko brothers may have been suggested 6 months earlier, but no serious work appeared to be done on it until French was asked at Steinway.
4) Others?
Dennis
1) Basically admitted in his interview that he is fine with deceiving the public about the amount in the middle (since he was still making good money from the stream) and because he would be playing hard.
2) Is on tape with Sword (per French) saying that he is afraid of Shane's break and that he won't bet anything in the match, but he will play it for free (being paid 15k guaranteed). I believe this to be the case. So Dennis was willing to play another match lying about what was in the middle.
3) Appears to be lying about not understanding what was in the contract, when it was read to him at least twice. (No reading skills required). This is based only on French's word, but I tend to believe it.
4) He took $6500 from French for DCC for expenses, without telling French that his hotel and entry fees were covered, since he is a past all-around winner (except for BigFoot match that wasn't covered). When French confronted Dennis, Dennis refused to give money back and said that the money was in case Dennis didn't win anything, he would still make money. (Very shady and I can't believe he thinks he's entitled to free money like that).
5) Took the 10k check for the Shane match, and as of the French interview, hasn't returned it like Shane did. According to French, Dennis had already sent it home to the Philippines.
6) Others? – besides being a sore loser and not shaking hands.
