I would pick up Dobson, he has significantly more upside and continues to solidify himself in the lineup. He's also not the injury risk that Amendola is, and doesn't have to compete with Edelman for targets from the slot receiver position.
Also I thought I had lost to a BYE starter in League C but I ended up winning because lol TY Hilton.
I'm not surprised you won Dubs, it came down to a TE vs a K, which is a complete toss-up depending on the night. Unfortunately this is my second loss of less than 3 points in a row in that league and I'm continuing to spiral downward. Hopefully I can bounce back next week when all of my WRs return from bye lol
