49ers beat writer Matt Maiocco believes Michael Crabtree is still the team's best receiver.
He has yet to practice since the opening day due to a right leg injury. It remains to be seen whether Crabtree will be on the field Friday for the first time with the 49ers in the exhibition season.
Veteran Randy Moss does not figure to see much action in the exhibition season. But the rest of the receiving corps should provide some interesting viewing.
I expect the 49ers to keep six receivers -- Crabtree, Moss, Mario Manningham, Ted Ginn, Jr., Kyle Williams and A.J. Jenkins -- on the 53-man roster.
