I never said Fields was a lousy prospect. Neither Aaron Rodgers and he dropped like a stone. Sometimes a player will get a lot of pre-draft negative information spread about them and it hurts their draft stock. It happens a lot. Just as much other prospects get too much pre-draft buzz and then get over drafted.
I said it isn't likely that Fields would drop into the 20s, but I wouldn't be surprised if it happens.
I doubt the Redskins will take him. They just used a mid first round pick on Dwayne Haskins just two years ago. I am guessing that they will give Haskins this year to prove he can be a good starting QB before they move on from him.
And besides, Washington has the 19th pick. If they take Fields there, is it really all that much different than him dropping down into the 20s? It is one pick away. When the draft process started, many people expected Fields to be the second pick in the draft. If he goes 19th, that is a massive drop.
