"When in doubt, a team should draft a player at a position of need for which there is the biggest disparity in results between a player drafted earlier and a player drafted later."
There are some Interesting data points for a tie-breaker system regarding prospects, though it is a bit of a "chicken and egg" scenario. What it basically said was the sweet spot for getting a five-year starter at ILB is the guys taken in the 25-46 range over similar prospects at other positions, otherwise there wasn’t as much difference in waiting.
Cornerback, on the other hand, in the first few rounds is much more so “take the corner".
IoW: If TT had Stephone Anthony and Randall graded evenly, odds were slightly better that Randall was going to turn out to be a five-year starter. And if he had Ty Montgomery and Paul Dawson rated similarly and he felt a KO return guy/4th receiver/backfield weapon was as big of a need as ILB, taking Montgomery gives him a better shot at having that long-term guy.
Getting back to the chicken-and-egg scenario, though, is one of the reasons WR odds are good in the second and third round is because of TT's success in taking them there.
So, using this idea, if TT felt the other positions were as big a need as ILB, he played the odds with his selections.
Of course, that doesn't account for if that feeling was correct, but that's a whole 'nother can of worms.
