It's more than reaching. You'd basically be drafting a player to pay him $12m - $15m per season to sit on the bench to back up Tua.Agree, don't reach.
When Miami could theoretically, select another player, at a different position of need and actually play him.
It just doesn't make any sense. To pay top 5 money and sit him. All while your still paying Tua, $50m plus per season. That's wasting valuable money and resources.
