If you like Jordan Love, you see comparisons between Love and Patrick Mahomes. Love has a tremendous arm - he can make throws that most other QBs can't. And he was very good in 2018 when he threw 32 TDs against just 6 INTs.
But he's a risk. Last year, he threw just 20 TDs against 17 INTs while playing against relatively weak competition. His Yards/Attempt dropped, his completion percentage dropped, and if you watch the highlights, there are a number of plays where he fails to see opposing defenders, fails to see open receivers, makes lazy throws, or simply throws the ball up for grabs. If he can eliminate those plays, he can be pretty good.
Personally, if you've already got a young QB that you like, I'm not sure Love would be worth the gamble.
