re: 5 straight years we have picked a Defender with our first pick in the draft

Saints are definitely a clear BPA picking team. Do know that need does factor into the equation though. The Saints might have Geno Smith rated as a top 15 player but that doesn't mean he is top 15 on their big board. There is a place though where value overwhelms need. That is how we picked Deuce. They invested a whole draft into a RB two years earlier. RB was very low on the need list. He was just that good (and proved it) that they couldn't pass on him at #23.

The only offensive players that I could imagine pressing like would be Cooper or Warmack. (Top 3 OTs definitely gone before #15 on my board) I don't envision a scenario of that happening though.

Odds are this year that there is a #15 worthy player that fits need as well.
