I want you to imagine something. Imagine you have been drafted in the second round to the NBA but get cut before the season. The OKC Thunder pick you up in the off-season, despite you not having played a game in the NBA. Your role within the team is to be the third string point guard. Oh no, Cameron Payne is injured. Now you are the primary back-up to the best point guard on the planet in Russell Westbrook.
Now, your every move on the court is heavily scrutinized. Every time you run the offense the team leader is resting.
