Here is my column from the just-completed Raiders/49ers exercise tonight at the Oakland Coliseum. There are so many things to write about because every play means everything and nothing at the same time.

I didn’t write about Alex Smith because the real season is near and I’ll write about him then — same goes for Jason Campbell, if he can play when the season starts. I must say, however, I never saw Darrius Heyward-Bey look so good.

I wrote about Mike Singletary and his hard hard attitude, which I admire. I hope you find this subject interesting and enlightening. To read my column click here.
