Here's the deal on Funchess. Cam has a tendency to throw high passes. Benjamin thrived with Cam last year. I wasn't high on him before the injury because I expected Corey Brown to the be the 2nd WR for a good chuck of the 2WR formations. Brown (Also know as Philly) is the speed guy.
Before injury:
WR1 - Benjamin
WR2 - 2/3 Brown / 1/3 Funchess
WR3 - Bersin/Ginn/Cotchery/Boykin
After injury
WR1 - Funchess
WR2 - 3/4 Brown / 1/4 Bersin
WR3 - Cotchery/Ginn/Boykin
The talk here before the injury was about keeping 7 WRs because how good they looked in camp.

Notice the announcer say Funchess picking up right where Benjamin left off? Kind of telling IMO.
