There's no conspiracy. Mara hires the GMs and has a voice in the hiring of the coach and also the major money moves, including top draft picks. So in hiring the GMs he is finding someone who aligns with his sensibilities. That's not bad or uncommon. The problem is, Mara's sensibilities when it comes to football and team development, and player personnel are usually very conservative, predictable, and behind the times. His father was the same way. As a result, the GM, because he has similar ideas and thoughts on team building as the owner, won't waver too much from that conservative, safe, sensibility. The result is mediocrity...at best. Could you ever see a maverick or radical (in terms of how he looks at the game) working for Mara? So that is where his influence comes into play.
