If you already have Giles playing at least 15-20min at C and Bagley for at least 10-20min in small ball lineups (as his offensive skillset is best utilized as C with no one clogging the lane), thats 25-40min worth of Center play
--> Do not overspend at Center
If players like Deandre Jordan, Valanciunas, Gasol cost close to 20mil and players like McGee, Brook&Robin Lopez, Dedmond, Thomas Bryant, Ed Davis, Salah Mejri cost under 5mil (some might be over 5mil but some will be under)

I also would like to sign players that are effective playoff players. A lot of traditional centers struggle some in the playoffs when the opposing team really gameplans against them. By going small and forcing the center to defend behind the 3 point line while putting him constantly in screen actions, it gets harder for them. The value of those traditional Centers could drop a bit in the playoffs. Vucevic hasnt impressed this year, Cavs took advantage of Valanciunas every year and even Gobert as a best rim protector in the league had tough time against a team like Warriors. I really wouldnt like to pay huge money for a guy whose value decreases in the playoffs. Financially its smarter to get a good cheap option that you can use against those best big men if you need to.
Also we currently have only one decent sized playoff level 3&D wing. The value of those guys increases in the playoffs. Ideally you would have multiple players on the floor that a)spread the floor, b)has size and ability to defend multiple positions and handle switching and c)attack close outs from the perimeter. We currently have one that can operate on a level that is needed in the playoffs. When you can fix the hole at C very cheaply, you should really devote your recources to get these versatile 3&D wings
