The problem with asking if you would have taken anybody else over Wilson is you lose a top QB to get them. And without at least a decent QB you can't win. So then I guess you'd have to say all the QBs have to be at the top of the list.
I wouldn't take Ryan or Rodgers. I wouldn't take Manning from his Denver years, which this covers. Ryan is definitely not better than Wilson. I'd be happy to have Rodgers if I didn't have Wilson over that period, but not so much that I want to trade out Wilson. I don't think Brady would dell will with Carroll, so I wouldn't take him. Brees though? You at least have to consider that.
But if there was at least a decent quarterback in the pocket if no Wilson? Donald, Sherman, Gronk, Miller, Watt, Mathis, Calvin Johnson, Peters, Thomas, Whitworth, Yanda, Staley, and Lynch? Those are pretty hard to turn down.
If this is just going to be a "QBs are obviously more important, so all good QBs at the top", we're probably like 10 QBs deep before we get to Donald and on performance in that period of time Wilson should be higher than Ryan and Manning and right at the same ranking as Rodgers. So then Wilson ends up being 3rd or 4th. But that's not what PFF is doing here.
What's really cool about this list is to see how lucky we have been in recent years with great players. Sometimes it's easy to forget but how many other fans are going to look at this list and have an equivalent? Look at this:
4. Sherman
20. Thomas
29. Lynch
33. Wilson
39. Wagner
55. Chancellor
58. Brown
74. Bennett
77. Baldwin
Unless I missed someone, that's 8 dudes that are/were solidly Seahawks. That's how they'll be remembered. That's a disproportionate amount of awesome on one team.
