Rex got 2 years because he was a loudmouth buffoon hired to be a shot in the arm, winning team from the jump, and he failed miserably. Rather than instill the motivated and aggressive mindset that he was known for, he decided to hire 1 million coaches and rest on his laurels. He failed to get the team to buy in, a team that had spent the last two years crushing Rex teams.
He was a failure in every way. The Pegs HC decisions have blown up in their faces.
