I'm trying to compile a list of who is better than Cousins....For sure the following:
Brees (old)
Brady(old)
Rodgers
Ryan (great weapons)
Roethlesberger (old)
The next 4 are similar to Cousins
Alex Smith (getting old)
Carson Wentz (still too early to tell how good he will be)
Stafford
Wilson (if he didn't have a top 10 D, would he win as many as Cousins?)
After that, there are a lot of players that are inconsistent (Newton / Carr), Young (Trabisky, Winsten) or on the downside of their career (Rivers / Manning). If Rosen is a slam dunk, then maybe you take your chance and take Rosen number one. I like Rosen and would take him #1, but it doesn't seem that there is a consensus. After that, I think there are a lot of unproven QBs. Cousins is a pretty sure thing to get you 7 wins without a defense. If you have a good defense, he's a playoff caliber quarterback. Why would you not want to put up money for that, especially if the Browns have it?
