1) Smoking spring training, I know it doesn't count but, well, it doesn't hurt. I think the contract will give him more confidence which I think is a big thing for pitchers for some reason...
2) Much better support than last year, when he lost a number of close games
3) SP seems a bit weak to me this year. Most of the 'A' starters have at least a few question marks around them. Wood does have a substantially beefed up offense though and, if his stuff is on, he's certainly as dominant as anybody on the mound.
I like Sammy too, obviously, but there's some other OF likely to do as well. If he hits 66, that'd be great but I'm not counting on it for the Cubbies this year.
