I think #19 is not a bad spot this year, if we are looking for defensive help. It seems like a heavy offensive draft for the top half of the first round. Of course, a true downfield threat at WR could look great to McVay, and I love the idea of us getting bigger and more physical on the O-line, just because of how good our offense is with a run game, so there could be a great OL still there at #19. Couldn't argue if we drafted either.
That said, I really would like a scenario where we trade back 3-4 spots for at least a 3rd rounder, if the draft shakes up to be top heavy on offense. For example, if some combo of Mitchell, Verse, Murphy, Newton, Latu, Dejean are still in the wings at #19, any one of those would be a great addition, and that extra pick would give us flexibility in adding several good players later or trading up in the 2nd if we really like a player there.
