They are fixing the o-line and surrounding Tua with as many weapons as possible so there is little doubt about his future if he doesn’t take a big step forward.
They were likely never going to take a QB high this year. They still have two 1st round picks next year that they can use on a QB or package to trade up for one. If that happens, they’ll have a rookie stepping in with a better o-line and great weapons.
The plan makes sense to me.
