Dude had 24 birdies last week. Of course, he also had 6 double bogeys. But here's the way I see it... it's a helluva lot easier to turn double-bogeys into bogeys, or even maybe pars, than it is to average 6 birdies per round. You gotta be able to make birdies to win at that level, and he has to take some satisfaction from that, especially considering the length of his layoff.
That aside, ultimately it comes down to him being able to stay healthy and play. It's much too early in the process to be talking about major championships, because one week, as promising as it looked at times, doesn't automatically mean he's ready to take on the world again. If he can stay healthy for a season - that's a good start. If he were somehow able to win a tournament, regardless of the strength of field, it goes from good to great. Then maybe at that point and time it would be more legitimate to talk about his chances in major tournaments.
But he can't be too upset with the good stuff he showed last week. There was a lot more good than bad imo.
