Video: The Perfect Fantasy Football Draft (1.03)
I just don't think it's very realistic that you're actually going to get Chase Brown there.

STACKED’s take

Unlikely to fall to 1.03 in realistic drafts; passed for Kenneth Walker

The source does not select Chase Brown in the second round from 1.03, reasoning that it is not realistic to get him at that spot in actual drafts, despite being available in this particular mock draft. This reflects ADP concerns and the likelihood of Brown being selected earlier in real-world leagues.
