It's up to Tua. He is the one who spent most of his life preparing for the NFL. Regardless of others opinions It's his decision. It may be too hard for him to give up on his long term dream.
The Colts are going to have to stop Packers RB, Josh Jacob’s. At least slow him down. Have to believe Green Bay has looked at that Joe Mixon video over and over.
If the Colts can minimize Jacob’s and force whoever is the Packers QB (Willis, or his backup) to beat them, the odds for a Colts win will go way up.
