Purdue - What did we learn?

ESPN QBR has him at a 33.9 for week 5, 14th out of 16th B1G QBs and 79th in the country.  (Also, that 33.9 is miles ahead of his prior 2 games, a 15.3 vs Oregon St and a 11.0 vs Notre Dame.)

Counter-point:

Raiola's QBR for yesterday was 11.3 (out of 100).  He didn't play well but I wouldn't say he was that bad.  I would guess he really got docked for the INT (and sacks).  

PFF gave him a grade of 46.8, which - to me - seems like a more accurate reflection of how he played.

Po-tay-toe, Po-tah-toe.  Both numbers are bad w/in the context of their rating scales.

I lean towards QBR because it is a mathematical formula.  PFF is some guy's opinion watching the game (and that guy may or may not be very qualified).

Earlier you cited Card's QBRs in the teens as evidence of how bad he was.  Do you think Raiola was that bad?

I didn’t watch Card vs ND or Ore St, (and I’m not going to) so I can’t give you my opinion of his bad games compared to Raiola vs Rutgers.

My eyes told me Raiola was bad vs Rutgers.  Stats told me Raiola was bad vs Rutgers.  Therefore I am going to say Raiola was bad vs Rutgers.  

Was he worse than Card? QBR says they basically had equal performances, so in the context of QBR Raiola was “that bad”.

I am confident at this point in time saying Raiola is a better QB than Card.  This was Dylan’s first game with sub-60 QBR.  Card has had 10 sub-60 QBRs over his 16 starts for Purdue.

Raiola's QBR for the Rutgers game has now changed twice since the original number was posted after the game.  So it must be more than a mathematical formula.  It went from 10-something to 11-something and is now 6.5.  

And I'm not sure 134 passing yards an 1 INT garnering a 6.5 QBR while 234 passing yards and 3 INTs garnering a 58.1 QBR really makes all that much sense.

 
I would never rely on ESPN's QBR to rate quarterbacks. Their secret lab formula has a lot of holes in it.  

Plus ESPN's QBR came out in 2011, the same year iPhone 4s came out.  

And PFF is so Chris Collinsworth.   It is more useful, but $40 bucks for a subscription?  No thank you.  

With college football, you really don't need to look at ratings to tell who is good, who had a great game or subpar game.  And sometimes the basic stat line helps to prove it in addition to what you saw.
