It doesn't appear as if the Miami Heat and Tyler Herro are going to agree to an early contract extension. According to ESPN, there have been no substantive talks between the two sides, and an extension before the October 20 deadline is considered "doubtful" at this point.
I suppose something could change between now and next week, but unless there's some serious traction over the next couple of days, it does look like both the Heat and Herro are going to kick this decision down the road. For both sides, that may not be the worst-case scenario.
