Fantasy Upside
A longtime starter in Buffalo, Stevie Johnson will likely settle into the No. 3 receiver role in San Francisco. Given Michael Crabtree's injury history, that could be significant.
Fantasy Downside
No. 3 in San Francisco's offense might not afford a ton of opportunities.
Bottom Line
With Michael Crabtree, Anquan Boldin and Vernon Davis around, there won't be a ton of opportunities for Johnson to shine, especially in a run-first offense. But an injury could change that significantly.
