I have always said I have a 2-year rule for rookies. I want to see a QB play at least 2 full seasons whether I declare them a bust, average, good, or potentially be great. Roughly a decent sample size = 30 games or so. I wonder how many in here thought Peyton was a bust after he went 3-13 his rookie season and threw 28 INT's. A sample size of 10 or 20 games isn't enough to determine anything. Any QB can start off hot and play good or great for 10-20 games or so, then fizzle. I have my eye on Brock Purdy. Then, any QB can start off bad for 10-20 games and turn out to be good or great.
