As a senior, he helped his team to a 10–3 record and earned All-State honors after catching 28 passes for 1,028 yards as a wide receiver and tight end.

In 2004, as a junior, he played his first full season at defensive end and finishing with 33 tackles, 10 for losses and five sacks.

[3] His selection at the time was questioned because of his lack of production in college, but the team was high on his athletic ability and potential for their 3–4 defense.

For the most part of his career with the Cowboys, Hatcher was a reserve player (his first start was in 2010) and seen as a disappointment, until he re-signed with the team in 2011 after not receiving much interest in the free agent market.

He appeared in 15 games (14 starts), registering 20 tackles, 2 sacks, one pass defensed and one forced fumble.

[9] Hatcher and his wife Natasha have three sons, DiCarlos Jason Jr., Boston Kash, and two daughters, Tamia, and Journee Jane.

His nephew, Jeffery Simmons, a defensive end and first-round selection for the Tennessee Titans, credits Hatcher with being his mentor.
