I think MHJ is the best player in this draft. If he fulfills his potential, we're looking at a Julio Jones type player. Those guys generally aren't available in FA, as their teams are locking them up. This is a good chance to get a stud receiver that has very few flaws.
Caleb is better than Drake (not as athletic or accurate) and Daniels (too skinny). I don't think Chicago will pass up the chance to take Williams, esp now that they've floated Justin Fields. If they wanted Fields, they would say he's their guy.
MHJ>Drake and Daniels.
Go sign a QB and a couple linemen and continue to build around a stout defense.
Brady, Montana, and Mahomes were not top 3 picks. Good quarterbacks have been found up and down the draft board.
