I think the only semi-possible scenario -- it is still very low odds -- to get Watson from the Texans would involve two transactions:
a) moving up to whatever slot makes sense pricewise between #4 and #5 (very expensive already)
b) offering the Texans that pick -- where they immediately take a QB this year -- and whatever else in collateral they ask for.
In terms of draft pipeline it most probably would set us back by 3-4 years while also paying Watson 10.5M, 35M, 37M (all fully guaranteed). On the flipside the risk is much lower than just doing a) and going for a rookie because you already know who Watson is. Also, Deshaun is pretty young (25) so you'd look (hopefully) at a long term investment.
It would open a window for us to easily compete for a title in the next 2-3 years until the missing drafts really catch up and then we either would have to start backloading contracts Saints style to prolong the party or just accept another rebuild but this time with a franchise QB already on board.
Of course that is close to the ideal case because injuries and other season changing stuff can happen in an instant as the Saints experienced in the last couple of years.
The final piece of the puzzle is whether BB and McDaniels wouldn't actually prefer developing a young QB themselves and sculpting him exactly to their vision. This is something nobody has really talked about but I can see them being excited at a chance to do that.
