He threw for 3,567 yards, 32 TDs and 6 TDs in 2018.
In 2019, Love lost his OC, his entire starting offensive line (1 OL with experience returned), his starting RB, and 80% of his WR production from the previous season.
Despite that, he still put up 3,402 yards, 20 TDs, and 17 INTs this past season. He's not flawless (no college QB prospect is), but he drew nothing but praise from the NFL coaches that worked with him this past week at the Senior Bowl. He spun the ball well all week, and in the Next-Gen stats testing, he blew all the other QBs away.
Utah State didn't utilize his legs much in their offense, but he showed Deshaun Watson-like power and quickness running zone read in Mobile this week, blowing past front 7s consisting of some of the best collegiate players in the country.
Is he the next Patrick Mahomes? Who knows. But, respectfully, he's definitely not Jameis Winston 2.0.
"Improving on his flaws" to me is:
Reading more than 1 or 2 receivers on each passing play.
Anticipating the defense.
Finding the open receiver.
Not holding the ball so long.
So many things that keep him from being a top 10 QB.
He has not improved his flaws from college.
