Jim:
In compiling my stats and making the observation, I deliberately chose the top 10 (and ties) for this reason -- all of those guys (save Casey, probably) had a reasonable chance during the last two days of the tourney to win the thing. I don't have the blow-by-blow, but each of those guys save Casey either at one point Sat. or Sun. either had the lead, tied for it, or was within a stroke or two of the lead.
To my thinking, it almost doesn't matter what someone's stats were relative to the entire field -- it matters what they were relative to those who had a decent shot at winning the thing. Based on that criteria, Johnson's driving accuracy just stands out as much better than anyone else in the top 10(Taylor was next at 73 percent, and then it slipped to 66 percent for Harrington. Johnson hit eight more fairways than Harrington, or two per day. That's a lot. He hit 10 more than Sabbatini, 14 more than Woods, and 15 more than Goosen. That's two to four more fairways per day than the runners-up. That's a ton.)
Sure, Johnson did very well hitting a lot of greens, but so did lots of folks in the top 10 (Woods, Goosen, Sabbatini Appleby, Donald and Taylor all hit between 43 and 45 greens). And Johnson putted well, but others in the top 10 putted better.
I'd agree -- it was a very good all-around performance by Johnson. But I think his success in driving accuracy, compared to the other contenders, is pretty telling.
