The 30-year old defender returned to the USA after four years in Denmark and despite a tough time results-wise with the Union, is happy to stay in his role as captain and help the expansion franchise move forward.
"Having the privilege of being the captain has been a tremendous responsibility and it's been something that's been really close to my heart," Califf said. "For me, it's an extra incentive to really try and do whatever I can to help us be successful. Not only on the field but in the team and in the community to help us get roots.
"If we can just continue and do a few things better, we can really make this into the best franchise in the league.
"I certainly believe that that can happen and I'm stoked to be a part of it."
