Wait. So you disagree that BB has more data with which to make the decision and more football knowledge than you?
While Mel Kiper and the draft industry pundits might have more football knowledge than me, they surely don't have more knowledge than BB who, if he retired tomorrow, is already a HOF lock for Canton. In hindsight, players like Vollmer and McCourty turned out not to be reaches at all. Players like Butler who dropped but were still picked in upper rounds turned out not to be good picks at all though most fans (and probably Kiper too) loved where they were picked it at the time. Not that BB picked Butler because of his perceived value to pundits and fans but, possibly, he regretted not selecting that year's under the radar version of Vollmer who was still out there at that spot.
The Combine and Pro Day numbers influence the Kiper guys and fans but often differ from what teams see elsewhere, particularly in their own private workouts. Scouting professionals and management of every team never reveal their true intentions unless, of course, you will use the top draft pick overall on a consensus franchise player like Andrew Luck.
Not every pick that is a reach in the opinion of Kiper turns out that way. However, many those players, who he believes are good picks because they were available much later than according to his ranking, turn out to be exactly what in reality is a consensus among every GM, as exemplified by so many passes. Such players were overrated by the wannabes but not by the pros.
Mel Kiper is no Bill James because, despite his obsessiveness for decades, the pros know that he is full of it.
BB is going to the HOF because, despite the inevitability of his mistakes, he brilliantly learns from each failure (though we aren't privy to his evaluations with his intimate associates). That's why he is a fixture after so long. When is the last time Kiper ever admitted making a mistake or even conceded that the professionals might know more than him (an inarguable proposition)?
Sleepers are never players that Kiper likes when picked. Sleepers are those ultimately good players like Vollmer when picked surprisingly high (based on fan and pundit perception) or unexpected successes, like Brady or Welker, who are selected low or acquired as an UFA without any fanfare at all.
If you have lots of information, then (in any endeavor), you need to trust your gut when you make a decision. That's what happens every time BB trusts his gut rather than considers opinions by fools like Kiper who have comparatively incomplete information. That's why, given his track record (with his share of failures just like everyone else), in BB we should trust.
