There's no argument Timo was worse last year. But the fact that one lineup did better than another lineup is not ipso-facto, that guy is so many points better than the other.
Who said that? Anyway that stats can guide you and can tell you in same way that Mozgov was worse last year, indeed
There are coaching decisions, personnel/chemistry changes, etc. Maybe LeBron wanted TT to succeed more than Timo. I have no idea and am not suggesting this merely suggesting there are a lot of "loose" factors when you base a player on the lineup stats and not his stats. Hence my suggestion that basing a players worth on how he does in a lineup compared with how another guy does in the lineup may not reveal a player's true worth, whereas his actual stats is a little more transferable from context to context. At least then you aren't mentally regressing four guys out of the equation. But whatever. Next year people will talk about how much better Timo is now that his knee is completely healed. Nobody will consider that maybe he wasn't as bad in the first place.
I substantially agree with you. There were many factors (the knee, personal issues, chemistry, etc, etc) that contributed in Mozgov´s performance with the starting lineup. You can see it in the stats above. Basketball-reference will say the same overall, for instance. You can compare both 2015 and 2016 seasons of Mozgov
FINALLY: Speaking to small sample sizes, it doesn't strike you odd that the same lineup w/o Irving but with MoGotti, noted weak defender is 50 points better? Does that not make you question how much that might fluctuate? What is the "error-range" on +/-? HOw much is it garbage time? Or on a back-to-back. When you're only talking about 100-250 minutes that's a fairly small sample, I'd think.
I tought in the sample size too, 251 minutes aren´t a lot of minutes. But you can use other stats that can tell you (or guide you intuituvely, if you prefer), the same history: Mozgov was, as you say, worse last year, and a
below average center as a whole

You can see deeply the performance of Mozgov, +/- per 100 possessions on court vs off court, PER, usage, win shares... etc, etc, etc, etc... some stats will be more accurate that others but all will tell you the same fact
