2. Not adding better wide receiver depth
The Atlanta Falcons went into the season putting a lot of trust in Mack Hollins. While the offense had weapons elsewhere, you cannot operate in the NFL without a good number-two receiver.
Drake London ended up being the only threat at wide receiver for the Atlanta Falcons and that is unacceptable. Hollins, Scott Miller, and KhaDarel Hodge should not represent your receiver depth.
Along with the next position on this list, the Falcons got complacent thinking they could get by with 'good enough' players instead of being aggressive.
