He's more explosive than Bosh. His best comp is AD. When I was scouting this kid, the only limiting variable to his game and the rate at which he would develop into stardom was dependent upon how expansive his game would become away from the hoop. The more areas of the floor which he could attack the more viable and versatile of a threat. This would set up going to work on the interior. Basketball is simple because it is a game of speed and power (along with fundamentals), or think quickness and strength. All great players have this combination. Your first step is a proxy for speed or quickness.
Harden who we see next could go down as the greatest scorer in NBA history. Don't @ me about his foul baiting, I am aware of it, I don't like it either, but that is being smart as much as cheap. Harden has surpassed Kobe and LeBron as a scorer. He's in the realm with prime Jordan. Now here's why I bring him up Harden in the context Bagley. When you try to crowd Harden he will drive through you (strength). When you give him space he will go by you (speed). When you have this combo of traits to go with the fundamentals (shooting, passing, dribbling), the defense doesn't know what to do with you. They are helpless to stop you. Bagley has an elite combination of speed and power game. Harden is a power guard with underrated first step. He's more of a power guard than Kobe and Jordan. For Bagley he will get more powerful when he adds 10-15 pounds of muscle. But he has that foundation in place. So many fans would not see a correlation between the Beard and Bagley but it exists!
The Spurs had to play off MB3 because of his first step. So he can take the open shot and if they crowd him, he goes through them. This is what Harden does too. There are fans saying Bagley holds the ball too long. I don't think so. He's sizing up the defense to make the highest percentage play. In his mind it is not if he is going to make a play it is how he is going to make it. All of this is to say no one should be particularly surprised by the game Bagley had last night. All the tools are in place, including the work ethic to refine his jumper.
