Jason approximately averages a double double (PTS, REBS) handing out at least 3 apg with incredible stamina as he does that averaging approximately 30 minutes in a consistent basis. Adding, his 2pt FG percentage must be very high (>70%) as he is very effective on his shots. Moreover, you would expect at least 1 three point make per game considering his position (PF). Jason can play defense nearly every position as he is comfortable guarding bigger (size wise) players as well as smaller, and he is very effective on the ‘heads out’ defense and switching to the guard and he likes to guard players on the post. He could also be defined as a hustle player as it won’t be strange at all to see him fall for a charging foul during the game. Also, he is a very efficient Free Throw shooter as he gets to the line a lot. Finally, reading and understanding the game is probably Jasons most powerful characteristic as he makes the right decisions at the right time to help his team win. Even though Jason hates to lose, what makes him a winner is that after a loss he will work even harder, especially on what he had done wrong in his previous performances so he can get better everyday and once again, help his team win.
