Well you have to compare with other franchises because you have to benchmark your performance. That is how you measure performance no matter how you look at it. That's what Steve means when you grade on a "curve" (i.e. a bell curve). You can't just expect them to draft studs in the top 3 rounds every year, 100% of the time. It is unrealistic. You also have to look at the draft class because if the whole draft class produces 32-64 decent players, it's a bit unrealistic to expect us to nail 4 picks. Just go look at the whole 2013 draft class.
People who criticize Ozzie for drafting haven't looked deep enough (1) into the draft class or (2) into the comparison on how other teams draft. It is like they expect every player to be stars in the league.
Ozzie has nailed his Top 20 draft picks (Ronnie Stanley (6), CJ Mosley (17), Joe Flacco (19), Haloti Ngata (12)... Suggs, Reed etc)
