I'm surprised you call Boston a below-average offense after just praising the Nuggets team starting Lilliard, Lee, Chandler, Varejao, and Monroe. IP's team has a considerably better offense in the starting lineup without Gallinari. When you include Gallo in the starting lineup, this Boston team is equal or better on offense at every single position 1-5 (if you twist the frontcourt matchups) than Yoki's Nuggets.
First, I'm not sure what my "praise" of Yoki's team has to do with my critique of IP's team, especially when my praise was that Yoki's team was a solid squad that lacked top-end talent and spacing in the front court.
Second, considerably better?
Irving (22.5 points, 39.1% 3PT%, .553 eFG%, 5.9 assists) vs. Lillard (19.0 points, 36.8% 3PT%, .546 TS%, 6.5 assists)
Stephenson (8.8 points, 33.0% 3PT%, .530 TS%) vs. Lee (7.8 points, 37.2% 3PT%,.545 TS%)
Brewer (12.1 points, 29.6% 3PT%, .506 TS%) vs. Chandler (13.0 points, 41.3% 3PT%, .556 TS%)
Gasol (13.7 points, 46.6% FG%, .512 TS%, 7.6% ORB%) vs. Varejao (14.1 points, 47.8% FG%, .529 TS%, 16.9% ORB%)
Splitter (10.3 points, 56.0 FG%, .609 TS%, 8.8% ORB%) vs. Monroe (16.0 points,48.6% FG%, .527 TS%, 9.9% ORB%)
Yoki's starters outscore IP's, and they outshoot them. Lillard averages more assists than Irving, and Yoki's bigs kill IP's in offensive rebounding. Heck, Anderson Varejao even shot a higher percentage than Gasol on shots from 10' to 23'.
I'd say that those teams are fairly close offensively, with Yoki probably fairing better due to his better shooting and rebounding. IP's squad certainly isn't "considerably better" on offense, particularly when you exclude Gallinari.
