O'Neal was plagued by a wrist injury last season with the Boston Celtics, but did well during his 25 games played. His averages of 5.0 points, 5.4 rebounds and 1.7 blocks in 22.8 minutes were good enough for him to be the starting center for Boston.
Signing with the Suns is a great move for O'Neal to get his career back on track, as the team has the best training staff in the NBA and he can get fully healthy this season. Just ask Grant Hill, Steve Nash and Michael Redd; they'll attest to how effective the training staff is.
O'Neal should come in and immediately challenge Channing Frye for the back-up center position. Frye and O'Neal are two different players, as Frye is a three-point shooter and O'Neal is a physical, defensive-minded player. But both should get an equal shot to win the job.
Although, O'Neal might be exactly what the Suns need on their front line—someone tough who will come off the bench and provide a defensive presence in the paint. Frye certainly is more offensive-minded, so whoever gets more minutes could depend on the situation of each game and the philosophy of the coaching staff.
Either way, this is a great move for the Suns to bolster the frontcourt and prepare for the return of the 82-game schedule.
