To begin is the NFL Scouting Combine, where you have to perform well in order to improve your draft stock. Here, this will determine how well your player did in the combine. Do good, and your player will see his draft stock into the mid or late first round. Perform bad however, and your player will see his draft stock at the second round or worse, much later in the draft.
You will have to take part in the five drills that can label your player if you perform well. Do well, and your player's physical ratings will increase as well as your player's draft stock. Reaching to the A mark and outperforming from your expected result, will result in a A grade, as well as a increase to your player rating based on the drill. Getting an A grade on all drills is crucial to both improving your player's draft stock and ratings. There are the 40 Yard Dash, The Bench Press, The Broad Jump, and the 20 Yard Shuttle. Each drill impacts the rating based on it.
The 40 Yard impacts Speed and Acceleration, the Bench Press impacts Strength, the Broad Jump impacts Jumping, and the 20 Yard Shuttle impacts Change of Direction.
The Last is the Position Drills. The most important drill. Getting all eight attempt succeeded is the key to improving your draft stock. Each position has different drills, like for QB, is to pass the ball to the receiver in the circle, and for WR, is to run to the hotspots and catch the ball there.
Once you got a A grade in every drill, your player will be projected as a first rounder.

Next is the IQ Test, a test that tests prospects' NFL knowledge. While it's optional, it is however, a must in order to raise draft stock, and a chance to raise it by getting the answers right.
Getting answers wrong and scoring low, can cause your player's draft stock to drop. But score high, and it will soar into the first round.
During the IQ Test, there are ten questions, all selected randomly. And you will have to choose the right answer to that question when given. You are given a certain amount of time to answer, so try to think about what the right answer is to the given question.When you made a answer, you are moved to the next question. To get the answers correctly is to remember what the events are and what it is. It can be about what happened during the previous season, and even events that happened along the way.
Once you answered all of the ten random questions that are given, the IQ test is finished. How much questions you got right will impact your player's draft stock, with the results that explains above, can be positive or negative. And after that, is where the big stage awaits.
