Trading Cousins at this point would be dumb.
I didn't say they have to replace all 4 spots. I said it would be ideal but it's not going to happen. I said keeping Wilson over Hall is probably the way to go at this point and that Merriweather back healthy should take care of one safety spot. Also, that's what happens when you hitch your wagon to bad players. Hall was another of Snyder's moves and re-signing him to that deal after less than half a season restricted what you could with him until next offseason.
There's no way they'd even get the 4th rounder back they used to get Cousins. I think he can be a player, but he hasn't been used enough to even suggest he's worth dealing for yet. Matt Flynn played a bit and was 3 years into the league before he was signed by Seattle.
I'm entirely ready to get rid of Hall, he just doesn't make enough big plays to be worth his salary and/or his mistakes. Wilson is less an issue, but still not a #1 corner. That said, our lack of a pass rush makes our secondary look even worse. Orakpo being out is HUGE. He may not be an elite rusher, but he's a good one and creates the space needed for Kerrigan to get at the qb. As a tandem, they are better than as a singular unit.
I like Carriker, but I agree we can probably let him go and run with Jarvis Jenkins in his spot next year. A RT is a must as is getting Davis under a solid contract. Let's not break the bank to get him, but he'd be a big help to RGIII. We also need to find another MLB. Fletcher is a great one, but his days are numbered if for no other reason than his age. Need someone to take over for him in the future. I'd like to keep Merriweather if he's finally healthy next year, but we still need a lot of safety, hell secondary help.
