Seahawks drafting technique

As always, I'm very excited about the picks and looking forward to how they work out. They always make picks that go against conventional wisdom, which made be wonder: how good are they at it?
I read a while back that historically, 50% of draftees wind up starting in 50% of the games they play in. An interest stat if true. When I looked at their drafts from 2010 to 2017, they were at 39%. That's a little low, and the real performance was in '10, '11 and '12 - where they were at 57% and drafted 7 pro bowlers. In the remaining 5 years, they are at 29% and drafted 1 pro bowl player.
Makes me wonder, why so good early, and so poor later? Was it because Pete was just out of the college ranks and had a better feel for the prospects? Scot McClouhan was there from '10 to early '14 - was that part of it? Or is it just plane luck and will cycle even eventually? Is it possible their 1st 3 drafts made them think their smarter than everybody else (maybe they are) and so they'll focus there?
Certainly JS is a master at the trade game. I obviously don't know the talent answer, and am not qualified to say, just to wonder. It just seems .....
