Boston has-
Baseball- Boston Red Sox (2014 season), 71-91 bad
Basketball- Boston Celtics, so far 10-15 bad
Football- New England Patriots, 12-3 good
Hockey- Boston Bruins, 17-14-3 (OK)
In New York-
NY Yankees 84-78, NY Mets 79-83. Both had about a .450-.550 winning %, so they are crappy.
The NBA Knicks are terrible- 5-25.
Football-
New York Giants 6-9 (crap)
New York Jets 3-12 (I root for the Jets a lot, so this is really bad!)
Hockey-
NY Islanders, 23-10 (a .697 win %, not even decent)
NY Rangers, 17-10-4 (.548 %, bad)
Boston has 2 bad teams, one good team and one OK team. Most NY teams are terrible besides the Islanders, Rangers and maybe the Yankees.
