Draft at least two O-Linemen earlyish

TB12 signed with TB in March of 2020. The NFL draft was in April of 2020. Drew announced his return for his final season in February of 2020. That right there, should have alerted SP and the FO, to get a QB. Especially if SP knew he was coming back the following year.
Thanks, I think they didn't have a plan beyond Drew, then, once Brady was off the table.

It ties in with the 'all in' philosophy they ran with throughout the Loomis/SP era. Why draft for later when you want to win now? Of course, we can see what that's subsequently cost the franchise.
