Russell Wilson has proven much more in this league than Mahomes. Looking at long term stock, Wilson would be the safer pick. While Mahomes would have the most upside.
Ive seen too many QBs have really good years only to be flash in the pans. I need to see 2-3 years strung together before I completely buy in.
With that being said, I do think Mahomes is special and will be a good NFL QB for years to come.
