Lee is one of those players that probably doesn’t have buckets of natural class (like TJ or even Murphy).
But, he’s clearly the type of player who works very hard on what he is good at and that’s his explosive high impact running. He’s a strong guy and has clearly worked on the basics of the game to iron out some of his early defensive issues.
It’s absolutely the right thing to play him in reserves first. Even if it’s not a full game to start with it’s about getting his confidence back in his body.
