Chicago Bears general manager Phil Emery has had his up and down moments in his two-plus seasons in charge.
In his first offseason, he drafted a player who appears to be a bust (Shea McClellin) in the first round, but he found a steal in the second round with Alshon Jeffery.

Despite hitting on his first-round pick with Pro Bowler Kyle Long, the rest of his draft in 2013 struggled when forced into action last season.
