Same here. A big guy in the middle that helps both sides of the court. Hakeem, Shaq, Duncan/Gasol (PF but they can also play C)
If you had to pick one, it 100% has to be the SG/SF spot. Dwight is a dominating presence, but he doesn't get the ball when the game is on the line. Kobe, Wade, Pierce type players do.
Center. For the reason stated above. A dominant center can really anchor a team. You have a better chance of acquire talent of the star kind in the other positions than the C in this age.
Whatever position is currently the weakest or has the worst elite/great depth in the NBA. 15-20 years ago, that was PG/SG. Now it's easily PF/C.
Center/PF. A team that has PF/C on a max contract doesn't need to spend $5-7/mil on scrub centers like the rest of the league. They could use the $5-7 mil on a some decent guards, but it will only get you a undersized or mediocre C.
Star at Point Guard = leading a team consistently into the playoffs but will never win a ring Star at Shooting Guard = can win a ring but will need a solid big man to be paired with. also the most exciting position to have a star with. Fans love to think they have the next Jordan. Star at Small Forward = absolute worst spot to have a star at. Unless it's a special player like LeBron or Bird. But not likely. Star at this position these days are mostly Grangers, Gays, Melos. Star at Power Forward = Decent spot to have a PF but not as good as the Center spot. Center = need not only to be surrounded by perimeter players but a solid SG. Do not do what the Magic has done with Dwight if you have a star at C.
depends on how good your management is. If management sux then you gotta go with the PG, it is easiest to build around a superstar PG. If management is great then you go with C, highest potential for championships but it takes a long time to get the right pieces around the C.
