Goga type of player is what we already seen works well in Orlando. Poeltl is a better version of Goga who is locked in for seasons forward. Goga probably expects a significant upgrade in the summer, not sure he stays in Orlando. WCJ is 4 years younger but fails to be available consistently.
In Toronto, Poeltl is not the best fit for a rebuilding team, Carter Jr is theoretically the better fit alongside Scottie as a spacing center.
