Evaluating Sixers’ options if James Harden leaves for Rockets in free agency

The Sixers have a lot of cap space, but they might not have any if Harden walks. If that happens, they will have to sign only veteran-minimum contracts. Tobias Harris is an attractive target for a potential trade. The Knicks talked about acquiring Harris before their recent eight-game win streak. If Harris doesn't get traded, the Sixers might have trouble finding a suitable replacement. They might be forced to look for other options. It's not clear how much value Harris has. He will be an expiring contract heading into next season. There are no easy solutions to replacing him. Even if he stays, it's unlikely they'll gain nearly $36 million cap room to replace him, so they may have problems replacing other players in free agency.
