Even if the Miami Heat wanted to make a bold move at the NBA Trade Deadline in an attempt to fix their biggest hole on the roster (their need for a star player), they'll have to choose between keeping Tyler Herro or Norman Powell first. It's the one current headache that the Heat seems to be avoiding at this point.
In theory, keeping both Herro and Powell would be ideal. But if the Heat has any hopes of upgrading their roster with a star player, that seems like an unlikely scenario.
If Miami is going to make a trade for a star player, whether that's at the NBA Trade Deadline or next offseason, you'd have to imagine that it's almost certainly going to come at the expense of Herro or Powell.
