The biggest issue the Heat would face if he misses time is that he's pretty irreplicable (at least on their current roster). Their backcourt has a lot of replaceability (missing any of Strus, Herro, Robinson, Vincent, or Oladipo would have an impact, but the others could play more minutes to cover), while their frontcourt is very thin. Missing either Butler or Bam would basically guarantee a loss, and while losing Tucker wouldn't be at that same level it'd be closer than any other player on the team. Losing him would be comparable to us losing any of our starters (other than Jayson and Jaylen).
