"The skill set," Arians explained. "I think they both were similar sizes, arm strength, very accurate. Both moved around good."
Arians referenced Garoppolo's accuracy and high-end athleticism several times, adding, "You have to defend his legs as much as his arm."
It's an interesting comparison for several reasons.
As a senior in 2013, Garoppolo broke Romo's Eastern Illinois records for career passing touchdowns, yards and passing touchdowns in a season.
Although the more current iteration of Romo moves a bit more gingerly, he was an improvisational wizard, relying on his athleticism to escape pressure for the majority of his career.
