Bortles is ranked amongst the top three QB prospects that will be available in the NFL Draft in most people's eyes.
He may potential be in the frame to go number one overall to Houston Texans, fighting against either of Johnny Manziel or Teddy Bridgewater.
The Raiders target is seen to have the biggest upside to him out of the three, which means he has the most potential that hasn't yet been seen fully in college.
One of the reasons for this is that he fits into the NFL QB stereotype of well over six feet and he has a decent stature.
Manziel on the other hand has smaller stature and he may be classed as fragile in the big league.
Bridgewater also has his weaknesses, and his showing at his pro day did little to impress.
Bortles will have a chance to shine tomorrow, with his pro day coming just 24 hours after the meeting with the Raiders.
Sports analyst and former NFL scout, John Middlekauf, posted on Twitter today.
