They drafted him at least 3 years too early. Yes, I used hyperbole. They didn't view him as once-in-a-decade, they just viewed him as once-in-five-years.
The excuse that "he was too good to pass up, they'll not have a chance at a player as good in the next 3-5 drafts" is just lazy excuse making. It's ridiculous to think that no quarterback drafted after the 26th pick in the next 3 drafts won't be any good. I don't think you can look at Michael Penix (the autocorrect on that name is expectedly awkward), Grayson McCall, or Myles Brennan and say none of those guys are definitively worse or won't be available next season. And that's just looking 2 years out.
Packers could REALLY have used Tee Higgins, Chase Claypool, Shenault, Pittman, or even Mims far more than Love; might have actually helped the Packers get a single first down against the Bucs after 2 fourth quarter interceptions. Added bonus, those players would almost certainly have helped THIS year's team more as well, and probably next year's team too!
I think this is another instance of hyperbole.
Not knowing the inner working of the Packers' front office, this is my theory regarding their thinking:
The prospects they liked at other positions being gone, and a QB that they had a big grade on sliding down, they decided to invest in the future of the QB situation early for that dual reason: 1) not loving the other options and 2) really liking the player.
Their scouting department grades every QB every year. It seems to be the case that they especially liked Love compared to others that they could reasonably expect to be available where they expect to pick moving forward. It's absurd to look ahead two years and assume that current sophomores in college will be facsimiles of a particular player in the 2020 class.
You don't have to like it, but that's what I think happened. I like/understand the thinking in ways, and not in others. Obviously yes, they could have taken a player that would be more helpful in the present. They traded short term benefit for the potential of much larger long term benefit.
But posters like you, still up in your feelings about not drafting a WR, have to grapple with the reality that the team turned around and put up one of the best offensive seasons in league history, and that WR was definitively not the reason they lost in the NFCCG. Maybe just an ounce or two of humility that they have some idea what they're doing would be appropriate. Just a thought.
