for whatever reason it's been ignored by the report that Gaines played a full Euroleague season with DKV. (2006-07)
he wasn't outstanding back then, but clearly a quality impact player at the highest level of basketball in Europe. tough, great energy, good intensity on defense, quick hands.
he played 20 games (16 starts) and averaged 10.3 PPG and 6.3 RPG in 25 MPG.
in the same season he also played the full ACB season in Spain with a decent DKV team. (Rudy had his break out season, DKV finished the regular season 4th in Spain and made it to the semi finals.) he averaged 11.0 PPG and 7.8 RPG in 25.7 MPG.
I think this numbers are better suited to display his potential than Turkish league or ULEB cup.
however, I can't tell why he didn't get a contract in Europe, for sure it wasn't a quality question, maybe more of a salary question.
(he switched teams every year, usually an indicator for a player, who just goes for the best bid). maybe he just gambles and wait till a top Euro team gets desperate because of injuries or bad play from their foreign players. we always see some significant roster changes in November and December in Europe and there are always some players just waiting to jump on a team for a good (because desperate) offer.
but maybe he just wants a shot to get a spot in the NBA.
(he's from Houston, maybe he wants to be close to home and that's why he comes to the Spurs camp)
btw. I think 6'9'' is for sure a bit exaggerated. he was always listed between 201cm and 203cm in Europe and just from comparing to other players I also would guess he's somewhere between 6'7'' and 6'8''.
someone compared his game to K-Mart. that's not a bad comparison I guess.
and yes, IMO he's absolutely not a SF and also not a combo forward (like Gist). pure PF.
