Griese locked in on Galloway to the exclusion of Clayton. Simms will spread the ball more.
I think Simms will work out, but it won't be surprising if there are some growing pains. Expect big numbers out of a receiver one week, then he may disappear the next. For a little while, expect the Bucs receivers to be like the Patriots receivers. They'll catch a bunch of balls, but nobody can predict who will catch them.
