Sometimes we make this too complicated. Ted has now traded up enough to dispel that old saw. He has taken for need (Dix) enough that arguing he is purely BPA is foolish.
Ted Rules
1. If you have 8 players rated the same and can trade down less than 7 slots (plus whatever you can discern about other teams intentions) and get good value for the round, you do it (Lacy).
2. If you can get a higher round talent at a spot of need when you think he won't drop to your next pick, you go up if the price isn't exorbitant (Matthews). The price in picks has to be lower than the value you place on the player. I suspect T2 had a better than end of Round 1 grade on Matthews.
3. You value late picks because it gives you more swings at the fence and means you don't have to get all the UDFAs on your list.
Ted's drafts aren't anything revolutionary (except perhaps success rate). Hoarding of draft picks and eschewing FA are more clearly hallmarks of his approach.
If an ILB drops to a point of ridiculous value like Matthews or Rodgers (maybe Dix?) he will explore trading up. If one falls to him and is at least even with the best talent on the board, he will take that position. This assumes that trading down doesn't make sense.
But he won't betray the rules of value just to take a need position.
