1. Will he run?
Mariota will likely forego all of the times drills at his pro day, considering how well he performed at the NFL Scouting Combine. There, he recorded a 4.52 40-yard dash, the fastest of any quarterback, along with 36-inch vertical jump and a 121-inch broad jump.
2. How will he perform on the chalkboard?
After running a unique offense in college, scouts are concerned with how Mariota will be able to digest concepts in a pro-style offense. "I think the chalkboard sessions are going to be important for him because it's such a departure," NFL Media's Brian Baldinger said. "Should he go to any other team besides Chip Kelly (the Eagles), there is a departure from what he has done at Oregon."
- How comfortable is he dropping back from under center?**
Scouts got their first look at Mariota taking three, five and seven-step drops from under center at the combine. He looked comfortable, but it was only a small sample size. The majority of Mariota's snaps at Oregon were from the shotgun.
4. Is he getting used to calling plays in the huddle?
At his press conference before his combine workout, Mariota said that he hadn't called plays in the huddle since he was in high school. He said that Kevin O'Connell, his former quarterbacks coach who was recently hired to fill that role with the Browns, suggested he practice calling plays aloud before bed every night. A pro day may not be the ideal scenario to showcase his progress in that category, but it will undoubtedly have scouts' attention.
