Walt “Clyde” Frazier knows what it looks like. He’s played on championship Knicks teams. He’s followed ones that have come close. The legendary Knicks player and announcer believes the current ensemble, fortified by the addition of Mikal Bridges, has what it takes to break through at some point soon after back-to-back trips to the Eastern Conference semifinals. “I see the vibes,” Frazier said Friday. “I see a lot of similarities with [our] championship teams, starting with the coach. [Tom Thibodeau] is a lot like Red Holzman. He holds the guys accountable, and they’re defensive oriented, and the players actually like each other. “I think this is going to be our year. Obviously, health is going to play a big factor into it. But if the Knicks can stay healthy, I think we can get back to our former grandeur.”
