Really? Witten we got in the third - we were shocked he was still on the board in the second, but we had a need a center so we took Al Johnson instead
So how is that BPA again?
We drafted for need with the first pick...and it didn't work out.
We got lucky that the BPA was still there in the third, and took him...and it worked out incredibly well.
Draft BPA. Almost period.
There are two exceptions I can think of:
1. I think this applies only to QBs and maybe top-of-first-round LTs. In those cases, where there's a clear BPA but he's clearly blocked from PT for several years, trade down. If he's really that clear a BPA, surely someone will offer something. You could argue other positions apply here.
2. If you're confident that your BPA will still be there with your next pick, sure, take someone else. The closer the grades of the players are, the more willing you should be to take some risk in this way.
And yeah, if you have two guys who grade out basically the same, sure, take the one where you have the greatest need. It's not like we really know that one guy is an 80.1 and the other guy is a 79.9: they're both around 80, so don't sweat it too much. Just don't pass on the 90 guy sitting out there to do it.
