Magic > AI
MJ> Kobe
Bird<LeBron
Barkley<Duncan
Hakeem<Shaq
Of the matchups though - only 1 is a complete walkover (Magic vs AI) - others are competitive.
Overall - I think consensus is A is more "competitive" - Aside from Kobe - is B really driven to want to beat the other side ? B's physical play is somewhat downplayed - aside from LeBron, all the guys on B played in the 90s and played when NBA was still a physical game and not the 3 point dominated game of today.
Need a guard on B who can hit the 3 more reliably and open up spacing on the court - let's say swap AI with Steph Curry. You have a more competitive matchup than people want to admit I think. Benches matter too - A cannot play 48 minutes with B without showing some fatigue - physical play wears on you and opens up the game for runs which keep B in this.
If I had to pick a team of bigger legends - A. But I'd say B is gonna keep this closer than anyone thinks over a 7 game series.
