I don't think its ignorant at all. Look at it objectively. A young, very average qb, and the worst Dline in football..
Now there are things that are in your favor. Very good Oline, Moss and Cooley are studs, and despite the horrible season ST had last year, the addition of Landry should help.
All great building blocks, no doubt. However, IF, and despite what you say, it is still an IF, Campbell can turn the corner and be pretty good, when is the most likely timetable for this to happen? Not this year, the best case would be next year. That would make your Dline absolutely ANCIENT, and news flash for you, they aren't any good now, let alone adding one more year on them.
You have very little young talent on your team to negate the age of your D line, your Oline, and this is probably Springs last year too. All of this because you avoided the draft like the plague the last few seasons.
So when the original poster says........"not a playoff team for quite some time", its really not that hard to look at it and see that he very likely is right on.
