MIAMI GARDENS — It’s only Week 3. And all the Miami Dolphins are right now is 2-0, albeit an impressive 2-0 with road wins against the Los Angeles Chargers and New England Patriots. With the team’s home opener next, the Dolphins will play a regular-season game at Hard Rock Stadium for the first time since they were clinching a playoff berth in last season’s finale against the New York Jets. Thinking about playing in front of his home fans against the Denver Broncos Sunday at Hard Rock Stadium had quarterback Tua Tagovailoa openly expressing his desires to deliver a championship for South Florida when he spoke to the media Wednesday. “We feel that the city of Miami has been waiting, and they’re ready for a championship,” Tagovailoa said.
