I've been wondering where Cousins might fit in this whole QB equation so I did some digging. The knock against Cousins seems to be a penchant for throwing INTs. He has thrown 9 INTs but 7 of those were in two games-the Eagles and Cardinals. Here's some game log info.
Jacksonville 22 for 33 250 yds 2 TDs 0 INTs 2 sacks
Eagles 30 for 48 427 yds 3 TDs 1 INT 0 sacks
Giants 19 for 33 250 yds 1 TD 4 INTs 2 sacks
Seahawks 21 for 36 283 yds 2 TDs 0 INTs 1 sack
Cardinals 24 for 38 354 yds 2 TDs 3 INTs 2 sacks
Titans 10 for 16 139 yds 0 TDs 1 INT 1 sack
One more interesting situational stat I found for Cousins-Red Zone passing this season
13 for 22 6 TDs 0 INTs 1 sack
Given the current situation, I wouldn't be averse to giving him a shot if for no other reason than "What the hell do we have to lose?"
