Draft at least two O-Linemen earlyish

Not looking to argue the point you guys are making, but was it because Drew didn't retire when expected, meaning Brady didn't come to NO, that basically borked the succession plan SP wanted in place? I may have all the timing wrong, though.
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.
