That's sounds good on paper but there really isn't a CB worthy of trading up for that's likely better than Kelvin Joseph, Rashad Wildgoose, or Paulsen Adebo in RD two.
I'd bet that all 3 are every bit as talented as Surtain and Horn at a much Cheaper price tag in rd 2-3.
I also really like Benjamin St. Juste and Keith Taylor Jr in the middle rounds who were outstanding at the Senior bowl.
