I'm pretty pissed off with those SpursTalk regulars who are willing to give Keith Bogans a free pass at the same time are discounting Haislip without giving the dude a chance to get familiar with the system.
The only reason why certain mediocre players stick around for a long time in the NBA is because they don't rock the boat. Look at Bogans style, he just stands there waiting for an open shot at the 3pt line. Yes, it's a useful skill, that way your offense always knows where someone camps. Unfortunately, we have both Finley and Bonner who already play that game!
He plays SG despite his lack of athleticism because he just doesn't have the skill set.
