Manning might not get in. Only reason why I give him a chance is because he's from the Royal Football Family and there's obviously huge influence there. He doesn't deserve it though, because he's never been a top 3 qb in the world at any point in time.
The only QBs that are a lock to get in are Brady Brees Rodgers and Big Ben (that are still playing).
And then you have Wilson, who will eventually get in barring an injury, Mahomes, and then as a prediction, maybe Lamar Jackson and Desean Watson if they somehow have long careers, but that is very iffy.
If Stafford ever wins a ring, or starts to play some good football in his 30s for the next 5 years, he will probably get in. Because QBs don't really hit their primes until early 30s, so I see a good 5 years left for stafford.
Rivers is done imo. The guy had Tomlinson Gates and a hole bunch of hall of famers on each side of the ball and couldn't get it done. Tomlinson was a once in a generation RB and they wasted him. That's a stain for Rivers.
Matt Ryan is guaranteed not to get in.
