LAKE BUENA VISTA, Fla. – Maybe you didn’t believe it when Jamal Murray reeled off 142 points across three spellbinding games in the first round against Utah. Or perhaps you weren’t swayed by his 40-piece in Game 7 against the Los Angeles Clippers in the second round that sealed Denver’s second 3-1 comeback in as many rounds. But if you somehow still didn’t believe that Murray’s growth was real, that his ascension to stardom hadn’t arrived, let Tuesday night’s Game 3 of the Western Conference Finals sink in. Denver’s emotional heartbeat saved the Nuggets’ season Tuesday night.
