I purposely threw in median into this discussion of averages to tease out what exactly you meant by average because I thought you were being unnecessarily vague and flippant with your earlier position.
Even then, I'm not buying your long winded answer and attempt to justify vague language by equating 'average PF' with 'average starting PF'. It's not the same thing, and no bit of median/average differentiating will make it the same. Now, if you had said that Baby had 'below average production for a PF' then you might have a case, because that's a measure of all PF production and would be skewed by the better PFs who play the higher minutes. But you said his stats are "below the average for a PF in the league," something that implies the median.
I also made a nod towards the fact that it's way too early to make any judgments based off 2 games. By taking his 2 game totals of "13 and 5 in 30 minutes a game" and concluding that it "is below average for a PF in the league" you were clearly making a judgment that pertained only to this year since you only used Baby's current 2-game stats and thus were not "speaking of comparing his production to average PF play in past years" as you now claim.
Average isn't a vague term. It includes all starters and backups, but since starters play the most minutes in the league their performance will naturally have a bigger impact than those players who play relatively few minutes.
Feel free to pretend I was "being vague" I wasn't. Average means average, not median! Just because a lot of people use the terms interchangeable doesn't mean I am. I didn't spell out my exact rationale and the numbers until your post, but I wasn't writing a term paper I was just pointing out a fact.
The average player in the NBA is a starter, not a bench player. Besides, if you're playing 30 minutes a game you're playing starter minutes. So when analyzing performance the starters should be included.
I wasn't being vague for flippant, I was being truthful. In 30 minutes 13/5 is below average for a PF in the NBA. As are Baby's FTAs, assists, and steals. Though he's above average in shooting % and turnovers.

I'm using past years numbers because average player performance is relatively static other than pace over the past few years. If I could have found per minute averages for the league in the two games I would have used them. But those numbers weren't available to me.
To say I'm shifting my position is ridiculous when I'm talking about a player being above or below average of course I'm using past year's play to determine it. I can't watch every single NBA game or tabulate every boxscore and crunch real-time averages. This isn't my job after all, despite my massive time investment.
There area couple of ways to look at average. One is to use Hollinger's PER, which, of course, counts points, rebounds, assists, steals, blocks, and true shooting percentage on a per minute basis. It is then normalized league wide so that the exact "average" is 15.00, and everyone else's PER is relative to that.
Last year, Richard Hamilton was exactly 15.00 and had similar minutes to Davis this year:
33.7 mpg, 18.1 ppg, 2.7 rpg, 4.4 apg, 2.5 TO
So that was "average" last year, when weighted for minutes, etc.
Others that were close to 15.0, similar minutes to davis this year:
Shawn Marion: 14.79 (slightly below average):
33.7 mpg, 12.0 ppg, 6.4 rpg, 1.4 apg, 1.3 TO
Kendrick Perkins: 15.08 (a few less minutes than BBD this year)
27.6 mpg, 10.1 ppg, 7.6 rpg, 1.0 apg, 2.1 TO
Jason Thompson: 14.6
31.4 mpg, 12.5 ppg, 8.5 rpg, 1.7 apg, 1.9 TO
Last year, Davis had a PER of 11.59, considerably below average. In 2 games this year, it is 18.98, which is certainly well above average. However, Most of that is due entirely to his Shooting Percentage. However, we know his percentage will not remain as high. so if he keeps his numbers where they are now this year, even when his shooting percentage goes down, he'd return to being slightly below average, as his numbers this year:
31.0 mpg, 13.5 ppg, 5.0 rpg, .5 apg, 0.0 TO
Are clearly a little worse overall than the 4 "average" players listed above.
There is another way to look at it. If you look at the total number of points scored, Rebounds, and assists in the NBA last season, and figure that each game consists of 256 "player minutes," you can figure out how many points, rebounds and assists the exactly average player would get per minute. Multiply by Davis's minutes this year, and you find that the exact average NBA player should, in 31 minutes, average around:
13.0 ppg, 5.4 rpg, 2.7 apg. Davis is a little above in scoring, a little below in rebounding, and significantly low in assists.
As such, I'd say Davis, this year, is "slightly below average."
