I can't disagree with a lot of that but having just Jones and Harper at SS would not be ideal unless you think Jones is a long term solution.
Finding a long term solution on the outside to pair with Norman with Bene starting NB would be awesome. Not to mention, the value at the top of this draft is there at CB.
And it definitely seems we've been sniffing around for a safety the past few drafts. The guys we have at safety right now are very solid in run support and know how to be at the right place at the right time, but can also be liabilities in pass defense. That's what we need to seek out at the position IMO, a young instinctive safety with his strengths being against the pass or just a balanced playmaker (rarer find).
What you describe almost sounds like Gerod Holliman out of Louisville. The kid was a poor tackler, but was an absolute ball hawk with 14 ints in a year (more than 1 per game). He also had about 250 int return yards and a TD on those. Also, the kid will probably be there in the later rounds because of the concerns with his tackling.
If we want a playmaker in the passing game for our secondary, then Holliman is the best fit, but can we live with the potential liability in the run game, assuming his tackling problems couldn't be fixed?
