Doug Flutie had something Manziel definitely doesn't have in my opinion. He was ridiculously accurate.
Flutie may not have been able to see over the line, but he could throw the ball EXACTLY 26 yards downfield and 13 yards to his left every single time. And he could deliver that ball 2.6 seconds from the moment he got it into his hands. So as long as a receiver was there. Well you were going to have a ball there too.
If you had a precision passing offense, Flutie was your guy. He could make a living off a timing route. Jump into a zone and start covering up those timing routes and suddenly he wasn't such a great passer though.
But then you suddenly discovered the OTHER thing that Doug Flutie could do... Move.
He could move around and THEN throw the ball to EXACTLY the right place.
That guy was a complete stud. Just a complete stud. If he had been 4 or 5 inches taller who knows what he could have done.
