Joe, a 6-foot-5 shooting guard, averaged 16.9 points and 4.1 rebounds last season. However, he missed six games in January and February due to a knee injury. Without Joe in the lineup, Arkansas went 1-5. With a healthy Joe, the Razorbacks were 19-7. “We are so excited to have Isaiah back,” coach Eric Musselman said. “He received incredible feedback from the NBA and got valuable experience with NBA interviews.
