NL East isn't that easy, MIA upgraded significantly and PHI/ATL have a strong pitching rotation...also you might see Strasburg getting lifted for a PH top of the 5th 1-3times (esp. if they keep watching his pitch count thanks to his injuries in the past), while Moore probably will finish 5IP in pretty much every game he doesn't get lit up.
Strasburg #1 pitcher for WSH, so he's also more likely to be slotted against the opposing no. 1 guys (which in their division would mean Halladay, Santana, Josh Johnson and Hanson/Hudson, that's at least 3 legitimate Cy Young candidates + Hudson, who owns a very good 2.6 ERA vs WSH over the last 3 years), while Moore most likely will be either slotted 3rd or 4th in Tampa's rotation (I guess 4th behind Hellickson, since Shields is the opening day starter, which puts Price in the 2nd slot and I guess Maddon will prefer to alternate RHP/LHP), therefore he will start against far inferior pitching since in my opinion the AL East pitching isn't that good (Tampa is great, but not too high on the rest) and especially not THAT deep.
You get CC, but behind that Nova is ok, but might have slightly worse numbers this year. Pineda/Kuroda imo will see a rather large decrease thanks to pitching at Yankee Stadium instead of Safeco Field/Dodger Statdium and at the same time facing far better offenses in the AL East. Boston has Lester, who is really good. But behind him Beckett is getting old and will almost certainly miss some time on the DL. Buchholz is a question mark after coming back from an extended layoff due to injury, Bard will have to prove himself as a SP and Aceves is mediocre...TOR has a decent 1-2 punch with Romero/Morrow, but Drabek has to pitch up to his potential and after that pitching is average at best and BALs pitching is crap...
So if Moore indeed will pitch the majority of his games against no. 3 or 4 starters, I'd def. go with Moore +1 in that scenario.
