2006 - Hawk, Colledge, Jennings, Spitz, and Jolly were all starters at one point
2009 - Raji, Matthews, Lang, B. Jones
2010 - Bulaga, Neal, Burnett, Quarless...I'm not even counting Newhouse or Starks
2013 - Jones, Lacy, Bahktiari, Hyde, Barrington.
Obviously your presumption that you'll never get more than 3 starters from a draft is false.
I'm high on Adams and R. Rodgers, but neither them nor HHCD really did anything above and beyond what was really expected from them their rookies years. R. Rodgers is the starter this year by default, not because he was a diamond in the rough.
By the way, who said 2014 was a bad draft? I think you need several years to evaluate a draft class. I simply stated that we are likely to lose a 3rd, 4th, 5th, and 6th round pick from a single draft class before they even enter a 2nd season, which is rare and somewhat disappointing, and that we'd like to obviously like to have less misses than that. That's hardly a controversial statement. I never said anything about the rest of the draft class or TTs performance as a whole.
