One thing to know: Romo still has three years left on his contract with the Cowboys, but with the emergence of Dak Prescott, Romo will almost certainly not be back with Dallas in 2017. With the contract, Romo can effectively pick who he wants to play for in 2017, and he reportedly prefers the Broncos. However, retirement is also an option.
