I read it wrong, sorry. I would go with Miami, but if you need another starter might pick that up instead.. If the player you are looking at would just be a backup, then by all means get Miami. In my previous post I was thinking about week 14 instead of 15.
I picked up Miami this week, and I like the matchup. If you already clinched a playoff spot I would just stick with Houston and get players for the Playoffs, if you need to win I would go with Miami this week.
