Interesting choices, and all seem logical. I agree on McIlroy since he's the hot hand at the moment. Day's been a little up and down, although he looks like he's rounding back into form, so I could see it. He was so close a couple times early in his career there, but hasn't been a factor the last 3 or 4 years.
DJ, however, is a bit of a mystery right now. He's been awesome when he plays, but he's barely playing. A win to go with a 2nd place finish, a 7th place and a 16th, but only four competitive events since November. For a World No. 1, he's like a ghost. I'm going to wait and see how he does this week, I guess.
I was kind of joking with JE above, but I'd put Rose in my top 3 guesses right now. He's playing very well (four top 5's including a win, and another top 10, in his last 6 tournaments) and he's been really close a couple of times at Augusta. He'll hit lots of fairways and lots of greens and if his medium range putting is on he'll be a force to be reckoned with.
Darkhorse pick to be a factor, with no particular reasoning behind it at all other than gut: Rafael Cabrera-Bello.
Is it too early for a Masters thread?
