I hear you. If you watched Beane's presser they simply had the RB and the TE rated higher on their board as far as value is concerned. They may have many of these WRs rated similarly so think they can find value in the lower rounds.
Sometimes teams trade up to prevent other teams from moving ahead. Case in point Houston thought Dillard was ready to fall to them but Philly jumped ahead and got him. They had to settle for Howard.
Likely when the Jags saw Allan fall, they stood pat. I also think the Bills had opportunity to trade back (based on what Shefter said on ESPN) but when Oliver fell, they didn't want to move.
That's exactly right! If teams stayed the same from year to year this "strength of schedule" would be valid. Teams change. Some get stronger. Some get weaker. Thus basic this year's strength of schedule on last year's teams is nonsense.
