Shouldn't change anything, there's a handful of athletes that had them. One of the more notables was Serena Williams who had a more serious clot in her lungs years ago IIRC. It does screw the Lightning heading in to the playoffs though.
The tanking talk is just silly. I've love to hear how you plan to get rid of Reinhart, Eichel, O'Reilly, Ristolainen, etc. for the last month of the season.
