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.
