My original question was what college quarterback does Burrow compare to--I probably did not make myself clear--not what pro quarterback do you think Burrow in the NFL will play like. The Eli Manning comparison is an interesting one, though Eli was never as dominant as Burrow was this past season.
I have seen the comparison to Tony Romo. But Burrow is on a completely different level than Romo when he was a college senior, and the same holds true for Garoppolo.
Eli Manning, the mediocre QB who could barely complete 60% of his passes for his career in an era where that's quite underwhelming.
That Eli Manning?
The OP has it right in terms of NFL ready cerebral QBs coming out of college. Peyton is the only comparison I can make in the past 20+ years of someone so ready for the NFL.
