I could very easily see six go in the first, don't expect it, but won't count it out either.
Fields, Wilson, Lawrence, Lance, and Jones all seem like locks for the top 20. The only QB left that will be better than a big project will be trask. All depends on how a team in those 20's feels about him(Pitt, NO, Tampa, Colts, etc).
JAX, NYJ, ATL, Philly, Detroit, Carolina, Denver could all take a QB. Thats 6 alone in the top 10. I won't be shocked if 4/5 of those top guys go in the top 10.
Need is massive at the position, demand is super high due to aging vets or busts. Supply is super low. Trask and Jones will probably go much higher than they should just due to that.
