Slow offenses generally destroy FCP, for future reference. If you had played Princeton, I think you win. 27 turn overs is a lot, but that's because of the hectic nature of your fast paced offense and his fast paced defense. I still think most times, you win this game and got a little unlucky.
I thought faster offence would suit better against FCP. As the opponent has many openings due to FCP, I thought there is no reason to pass the ball for at least around 15-16 seconds and shoot it with a good chance to score. Plus, as it can be seen, I had low level of offensive flow to play e.g. motion offence effectively.
The slower offenses don't actually always take 16 or more seconds on the shot clock on every possession. What it does instead is basically raises the threshold of what is considered a good shot when evaluating whether a player should shoot or do something else with the ball. Against an FCP, if you survive the steal attempt, you should get a high enough quality shot relatively quickly.
I checked on Buzzer-Manager to find the season where I knew I'd played an FCP team a couple of times (well, only once in league it turned out) and found an example there and in a PL game later. The first game was the league opener, where we were both new promotees, and we both ended up in relegation series at the end of the year, but thanks to training and not having completing my offseason shopping, I was definitely playing with a worse roster, on the road. I still lost, and deservedly so, but I think the Princeton kept it closer:
(89131579). (For comparison, our rematch we both played R+G and I lost at home by 2, 89-87). Notice I scored more points with a slow offense vs. FCP than I did with a fast offense vs. a 3-2, despite being on the road.
A better illustration of the slow offense against a bad FCP is the PL game from the same season:
(90252832). Now, of course, the defense was simply not anywhere near the caliber of my outside offense anyway, but I also scored 114 in the first three quarters with a Princeton, before the bench came in to lay bricks.
Of course, if the flow is bad enough the slow offense is asking for even more steals, so at that point you may weight it more toward a motion or even R&G if you're concerned about too many turnovers. It's just that R&G instructs the players to jack up a shot quickly even if it's a fairly low quality shot, which means you're negating some of the advantage you're getting by facing the FCP, while still allowing the turnovers.
