The man's written five stories for SI in the last year:
1) Omar Minaya - pretty good
2) Randy Shannon - decent, written in basically the same voice as the Minaya piece, and content to let the bizarre details of Shannon's life just sit there (the hermetically-sealed life, the estrangement from all friends and family).
3) Joba Chamberlain - overwritten, in my opinion
4) Jim Jones, Jr. - the decision to go second-person ruined it for me.
5) Gene Upshaw - wasted too much space with the ghosts metaphor, which overshadowed a basically interesting (though pro-Upshaw) take.
So basically his last four pieces haven't been up to his usual standards. And because he writes so sparingly, it's been 10 months since the last great Smith piece (in my opinion).
