It's a pretty tough gig being an import for the Sixers at the moment, they have so much pressure to perform and they are the easiest target for those looking to distribute blame for an under performing team, but for me the biggest issue is just the system they are being made to run.
All the players are not being utilised within the current system, especially the imports. Look at a team like the Hawks for example. Geordie seems to develop his offensive system based upon the strengths of his team. Clarke seems to emphasise the system over the players i.e. the system will get the results if players get to the spots they have to.
I love the way Geordie coaches his team. They make an effort to get Oscar three balls from the wings, Sav and Davidson's mid range games are utilised, Hurdle and Martin are encouraged to run the breaks in transition and get to corners, Deleon is given isolation plays and Gruber is their glue guy that gets second chance points. He coaches to the team he has and they perform close to their maximum potential.
Isaac you said the Sixers could have had Hurdle but I'm not really sure how much difference that would make in the Sixers system. I'm sure if SC was playing at the Hawks he would be running the break with confidence and have a series of plays run for him (i.e. pop outs on pick and rolls, swinging it in reverse on the perimeter, kick outs from Davidson) to ensure he got some good looks from the three to utilise his strength. It wouldn't surprise me if he averaged 10-12ppg playing his role.
One of the most frustrating things this year about the Sixers has been their inability to play to their individual strengths. Weigh, Gibson, and the imports are great three ball shooters when given open looks, but they never seem to get them. Schenscher is hard to contain down-low, but rarely gets the ball down low early and when he does he's usually triple teamed. Cadee, Creek and even DJ (compared to most 5's in the league) are great on the fast break, but we never see them in the open court. Petrie and DJ are great from mid range, but too often they find themselves out on the perimeter.
This team really could be good if their individual talents were utilised. I don't necessarily think the import should bare all the heat. Maybe the system should.
