I totally get what you're saying and to a certain extent I agree. However, there is only one DB in this year's draft that has a shot at getting INT's like Reed did and that is Hooker. If you're drafting a safety based on that... well, when Hooker went off the board there wouldn't be a safety the team could draft.
Like I said though: I get what you're saying and I do think that the team is going to be looking for DB's who tend to get their hands on passes. They won't be able to draft two or three guys though if they insist on that criteria. Somewhere they're probably going to take a DB that doesn't have high INT totals in this draft.
As for Peppers, at SS you don't expect a big time ball hawk. You want guys who can cover TE's, can take on blockers and can get to the ballcarrier quickly and efficiently. An enforcer type who can fire up his team mates with TFL's, sacks, etc. Peppers is all of those things. You always want INT's... but if you're going to get a guy who isn't a ball hawk in your secondary... SS would probably be the position to do it at.
I don't love Peppers but I do like him a lot and think he would be a huge upgrade over Church/Wilcox.
Desmond King is a safety prospect who tends to find the ball and I like him a whole lot as well.
In the end, I trust the team to get the right guys, which is what is most important. Not what I, you or any of us fans want them to do.
I'm not saying the Cowboys will be able to get a ballhawk with every secondary pick, but they should be able to find someone who has exhibited the ability more than Peppers. Peppers had 1 interception in 3 years. At a guess, that is likely less than anyone who is simultaneously slotted to go in the first 3 rounds at safety or corner.
I understand what football has looked for in the past in Strong Safety's; but I think the league at large is moving away from the in-the-box Safety. Now more than ever, Strong Safety's have to be able to cover and make play's on the ball. And I'm not sure if that really is Peppers strong suit. According to the scouting reports I have read he struggles when asked to cover. Fast, instinctive, athletic? Yes. Improvement over Church/Wilcox? Probably Yes. But does he go get the ball? He may have that ability, but he hasn't exactly exhibited it. Even as a linebacker, he should be making at the very least the occasional play on the ball if he actually has the talent to do so. Sean Lee, for instance, as a linebacker has exhibited the ability to make plays on the ball. If he had the height, speed and weight of Peppers, he would have already been moved to Safety for that reason. So while I get that Peppers could improve the Cowboys defense as a whole, I honestly think the Cowboys are looking for a different type of Strong Safety; one that won't be lost in the face of an empty set and 5 potential receivers.
But, admittedly, I've been wrong about what the Cowboys are looking for before. Based on what they have said, I suspect they'll ultimately be looking else where in the first round. And not just because Peppers doesn't fit the mold. It will also be because I suspect in the first round they'll draft a guy from a position group that is not deep like DE, S, and CB. More than likely, they'll draft BPA in the first round because they will feel they can address DE, S, and CB in the latter rounds, unless of course the BPA is one of those positions groups...then I doubt very seriously they pass him up...unless it's Peppers, than I think they may trade out of it, because I suspect there will definitely be a team that will want him. But that is just a guess.
