Do you really think Thompson would have drafted either Jameis Winston or Marcus Mariota if one of them would have still been svailable at #30 over Damarious Randall???
1) If Rodgers were turning 36 years old,
2) had been mumbling about retirement for the past 3 years,
3) doesn't show up for work,
4) and either of those two prospects were as promising as Rodgers (which they are not),
then absolutely!
QB succession should be a multi-year process. If you wait until one is
needed right now it's going to be too late unless you dump out to the bottom of the standings and Andrew Luck is on the board. What are the odds of that? More likely you end up having to reach for guys like Winston or Mariota, or even a Blaine Gabbert, Christian Ponder, E.J Manual, or any of the vast majority of drafted QBs who wash out or settle into journeyman mediocrity. And while you wait around a couple of years to see if they'll take the "step up", you suffer through some lost years.
Was Rodgers a need pick? Sure he was, just not for the 2005 season. But that's irrelevant. The position is so important and the preferred tutoring process elongated, you have to strike when the iron is hot in a multi-year range as the franchise QB ages.
