Again, teams will often take the Best Player Available even if it’s not a need position.

The Rams have arguably the best DL in the NFL, yet they still used their 13th overall pick on Defensive Tackle Aaron Donald.

That’s not a contradiction, that’s what teams do. They often take the best player available, even in the 1st round.

The Patriots took a QB in the 2nd round even though they already have one of the best in Tom Brady.

That's flawed reasoning. Jimmy G wasn't the BPA in the 2nd Rd. when the Patriots picked. You're assuming that's why the Pats picked him. The trade talks for Mallett are still in play, whether its the Texans or someone else. They clearly think they need an upgrade at QB, especially with Mallett at the end of his rookie contract. Jimmy was drafted out of need/depth, not BPA.

And as for the BPA theory, it doesn't always work. Case and point: Detroit Lions, esp. under Matt Millen.
