IMHO, we should be looking to get a top 2 pick for 2020, because whichever QB we like, there are unlikely to be more than 2 top QB's and teams are even less likely to trade the pick. While there are a good 3 top prospects today … generally the NFL finds a consensus of 1 or two top guys. I can't see a team with more than 4 wins getting a top 2 pick. If we win 5, we could be outside of the top 5 picks entirely.
IMHO, Tanking is going to require 0 - 4 wins. Any more and we're mortgaging the future to try to trade up a few spots.
