That's a pretty gratuitous over-simplification of a team. The first 3 rounds make or break your draft because of the resources that go into those picks, but "95% of your best players" don't come from those rounds. The Ravens roster is built like all the others, 80% of starters are rounds 3-5 guys. If you take a guy in the 1st or 2nd and he's not a starter you're setting yourself up to fail as the guaranteed contract on those guys will haunt you. Ozzie, like a lot of GMs, are far more comfortable taking 5 or 6 shots in rounds 3-5 than take 1 shot in rd 1.
And 98% of them pan out to be nothing. At best, you got Jarret Johnson or Bart Scott. Those guys don't win you championships. Ogden, Lewis, Reed, Suggs, Sharper, McAlister, RRice, Flacco, Heap..........those are the guys who bring home the trophies. Ozzie needs to get over his stupid comp picks and hoarding of junk round picks (4th-7th) and get back to successful top picks. He was the best for 24 years. Since 2010, he's been awful.
You have no idea what you're talking about. 98% of them don't 'not pan out' just like 95% of 1-3rd rounders make up your team which is another ridiculous claim you made. You realize you have to be bad to draft the guys you named? Ogden-4th overall, Mcallister-10th overall, Ngata-12th overall, Suggs-10th overall, Heap-31st overall(a 1st rd TE might as well be a top 10 pick at CB or DE value wise), Flacco-16th overall. The Ravens have been drafting in the mid-late 20s for the better part of the past 15 years. When we do have top half picks recently Ozzie has nailed those as well (Stanley at 6 and Mosley at 16). Getting HoFers like Lewis and Reed in the 20s is an extreme outlier and for you to assume we should just not draft the bad players and take all the good ones shows you know very little about scouting and development.
