The runway has been his the entire season, with Jimmy Butler nearly as often away as present, with Bam Adebayo uneven on the offensive end. So it hasn’t just been Tyler Herro seizing a moment; it has been Tyler Herro seizing nearly every Miami Heat moment. With Saturday night’s 119-98 victory over the Portland Trail Blazers just the latest example. This time it was Herro quieting several Blazers rallies as the Heat improved to 3-1 on a six-game western swing scheduled to continue Monday night against the Los Angeles Clippers at the Intuit Dome. “It’s reaching a level that it’s becoming a consistency, it’s becoming an expectation,” coach Erik Spoelstra said of Herro providing consistent relief at moments of need, of which there have been many amid this uneven ride to 20-17.
