Robin Lopez is well aware that the Nikola Mirotic-Bobby Portis situation might need a lot more fixing than first anticipated. Lopez’s hope was that there would be a healing period and then both players could sit down with the team, mend the damaged bridge and move on, but the fact that Mirotic won’t even return any of Portis’ attempts to call or text him is concerning. “Yeah, I’m sure that we’re all thinking that,’’ Lopez said on Tuesday, when asked if there might be more damage in the relationship than initially anticipated. It was last week that Portis and Mirotic had an altercation in practice, leading to Portis punching Mirotic and sending him to the hospital with two broken bones in his face and a concussion.
