Understandable. I think Geno has a much higher floor than Darnold. You know what you're going to get with him. With Darnold it could go either way. He could show some of the things he learned last year and continue to play well (in which case you have a 28 year old franchise QB for cheap), or he could revert back to bad Sam without the terrific surround he had in Minnesota. I suspect it will be somewhere in between.
One thing's for certain: if Sam completely fails in Vegas while JJM lights it up in Minny, KOC's stock is going galactic.
