The Phoenix Suns made some massive roster changes this offseason, but the most intriguing addition by the organization was center Mark Williams. Adding another layer of intrigue to his arrival is the fact that Williams is entering the final year of his rookie contract, and so is due an extension. Contract extension for Williams must include injury protections. Vecenie rightly predicting that Williams' next deal is going to be complicated - because although he's a productive player - his injury history is massively concerning. It's not like he's a bad player on the court either, there's a reason the Suns traded for him after all.
