Ira Winderman says the Miami Heat should keep the 15th roster spot available for someone like Zach Lavine: “Heat essentially have enough space under their hard cap to sign a single player to the veteran minimum. So you wait not only until something better comes along, but rather something best. When you have one bite at the apple, it had better be a pretty darn tasty apple (something perhaps, eventually, of the Zach LaVine variety).”
