This. It's not that they want to find their future QB, it's the way they went about it, given their current situation, wastes a lot of the benefit you get from taking a QB in the first round. Love will get a cheap, 4 year deal with a team option of a 5th. It's super beneficial from a team perspective, because having your starting QB making say $5 million a year is peanuts, so you can spend that savings on other players. Green Bay isn't going to be able to do that as easily, because Rodgers is already taking up a large portion of the cap and will next year as well. And he carries an absolute monster dead cap number for the next two years, so they can't really unload him either. Barring injury, the earliest this pick pays dividends is 2022, when the Rodgers would count a whopping 39million against the cap, with "only" a 17 million dollar dead cap number. That's the exit point for Green Bay, but it still will cost them.
Couple in the Covid factor and the unknowns it brings, and you could be looking at a stagnant salary cap as well. That would make things even worse for Green Bay.
That's just on the financial side of things. I'm not going to comment on Love's talent, as that's pretty subjective.
