This kind of thing happens sometimes. A player is said to be a 4th round pick and for a couple of months, everyone is mocking him to their favorite team in the 4th (or later depending on the mock draft sim).
Then, the pre draft process continues and a guys value rises up to a 2nd round pick and everybody is upset because they used to get him much later. Now, getting the same guy, they no longer have a 2nd to get the other guy they’ve been mocking in the 2nd round.
The guy’s value is what it is. If teams are now going to take him in the 2nd then you have to spend a 2nd if you want him.
That being said, I don’t know if I’d use a 2nd to get him.
