Yeah, seems to be a double standard at work.
-as fans, we get upset when fellow fans even SAY negative things about the Celtics, let alone if they actually rooted for another team or another team's player.
-as fans, i think we'd be upset if one of us, say, got a job in Cleveland and started rooting for Lebron (assuming he resigns).
-Many athletes clearly love sports...should they uproot their and their family's sports roots and start to root for teams in other sports that are in the city in which said player now lives and plays?
-For example, Celtics are my favorite team. But what if i woke up one day and it turned out I had a 95+ fastball with movement, a drop-off the table curve with plus control and ability to throw it with two strikes and a 12mph slower changeup. Let's then say the Yankees offered me 15 million dollars and Boston offered me 10. Would i take the boston job just because i hate the yankees? Heck NO! I'd pitch for the Yankees. And i'd try my hardest when pitching against the Red Sox or any other team. However, I would NOT root for the Giants, the Jets, the Mets, or the Knicks or the Nets. I'd still hate them. And I would absolutely show up at Cetics games in the offseason and give Rondo a high-five.
