Last week, we considered whether 35 offensive snaps and 16 pass routes were enough for the San Francisco 49ers to fully assess second-year wide receiver A.J. Jenkins.Turns out it was enough.The 49ers traded Jenkins to the Kansas City Chiefs for receiver Jon Baldwin, another disappointing first-round draft choice. This move is good for the 49ers in that it shows they'll move on from a disappointing player without carrying him on their roster just to keep up appearances.
