On this week's Mailbag, Gill Gross responds to your comments about the Jannik Sinner anti-doping violation saga that has culminated in a settlement between he and WADA and a 3-month suspension. We discuss how the system could or could not be overhauled, the differences between recent Clostebol cases, why Umberto Ferrara wasn't punished and is now with Matteo Berrettini, the prevalence of TUEs on tour, the low concertation argument, why the timing of the settlement was so favorable for Sinner, and we'll five into player reactions to the news including Novak Djokovic.
