67 76ERS- CHET WALKER, WALI JONES, LUKE JACKSON
Do you want information?
Chet "the Jet" Walker was a 6'7 forward who is just barely not in the hall of fame.  He was good in the open court, and could also shoot well.(especially along the baseline).  He was a good rebounder and defender.

Wali Jones was a defensive monster who filled in at point for the injured Larry Costello.  He had a funny looking jump shot, but was a good shooter and would drain long one-handers.

Luke Jackson was an intimidating defensive power foward.  He was one of the NBA's fist Power Fowards.  He had a good outside touch, and was a good rebounder.  He was left handed.
