Posted because I don’t trust Wiki
You can’t extrapolate stats, that’s your problem.Um...so it looks like you are confusing a few things. in effect, QBR measures the efficiency of the qb play. It doesn't measure how talented or how good a qb is. That is determined over time.
For example, is Patrick Mahomes the greatest NFL QB of all time? He certainly destroys Brady's stats...so Mahomes is better, right? Or do we have to look at their careers and the 6 rings Brady has?
One season is one season. But let's take a look at your example.
Did Trubisky have the 3rd most efficient season? Let's compare him to Rodgers since Rodgers is lower on this list than people would expect since he's considered one of the best qb's in the NFL.
Trubisky's usual counting stat numbers 2018...
66.6%_____3223yds_____24 TD's/12 INT's
Rodgers's usual counting stat numbers 2018...
62.3%_____4442yds_____25 TD's/2 INT's
Most people would say, Trubisky has a higher completion percentage, but 1200 MORE yards and 1 MORE TD and 10 fewer INT's...it's a no brainer.
But the problem with counting stats is...they are skewed massively by # of attempts. Now let's look at some quantifying stats...
Trubisky's
434 attempts_____5.5% TD_____2.8% INT_____24 sacks
Rodgers'
597 attempts_____4.2% TD_____.3% INT______49 sacks
Rodgers had an extra 163 attempts to get more counting stats. Trubisky has a higher TD % throwing the ball though Rodgers beats him in INT %. But Trubisky took a lot fewer sacks which typically kills drives. Let's equalize the numbers (give Trubisky nother 163 more passes) and see how this works...
Rodgers's usual counting stat numbers 2018...
62.3%_____4442yds_____25 TD's/2 INT's
Trubisky's new numbers...with 597 attempts
66.6%_____4433yds_____33 TD's/16 INT's
Now, it's not so cut and dry since Trubisky clearly has higher completion %, almost the same yards but 8 more TD's. Rodgers has 14 less turnovers...so interesting thought as to which QB you'd prefer.
But let's add the last 2 elements we can see without reliving both of their seasons.
Trubisky rushed for a few hundred MORE yards and 3 TD's compared to Rodgers' 2...so now Trubisky has him beat in completion %, overall yards by a couple of hundred, 36/16 versus 27/2 in TD's while Rodgers beats him in turnovers.
Last element I see is sacks. Rodgers took 49 while Trubisky had 24 with real attempts. Equalized it's 49 sacks for Rodgers versus 33 sacks for Trubisky...that's 1 extra sack a game!
Trubisky had a better year overall in terms of efficiency. Higher completion %, more yards on avg (rushing and passing), much higher TD rate, fewer sacks,,,but Rodgers does beat him handily in turnovers.
Lastly, don't focus on Mayfield being 'ranked' 23 or 24th...he's rated as above average and I think that is correct.
For example, is Patrick Mahomes the greatest NFL QB of all time? He certainly destroys Brady's stats...so Mahomes is better, right? Or do we have to look at their careers and the 6 rings Brady has?
Why would you say something like this? Where did anyone say Mahomes was better than Brady?
Did he have one of the greatest statistical seasons of all time? Yes.
That’s just a dumb argument.
Pretty good considering he didn't start trying until like 10 weeks in.
Consistency is the key.Brady>Mahomes. Brady has won over, and over again. Mahomes will have teams studying tape this year. Kid is great with a rocket arm, but only time will tell how “great” he truly is.
If Mariota had as many attempts last year as Mahomes, he would have thrown 19 TDs.You can’t extrapolate stats, that’s your problem.
Stats are what they are. Stop making up additional stats.
Mary had 13 td passes, not “Mary had 18 td passes if you count the drops.”
That’s the beauty of stats, they aren’t objective, they are what actually happened.
The difference between QBR and QB rating is that despite a crazy formula for rating, it’s numbers based not ESPN analyst quantified number where a human value is given to a situation that really doesnt have a quantifiable value.
I have never made up a thing. All backed by numbers and facts

Mahomes is better than Brady (Right Now)

Rating is used with the actual performance numbers, ie TD thrown, yards, YPA, etc. things that actually took place. QBR uses a hypothetical number given for certain situations.They both have made up quantifiable effects. QBR takes this into account on a play by play basis to understand the value of the stats. QB rating does this in a broader sense in simply deciding which stats are more important than others. Both are made up but based on numbers.
Ironic you like one 'made up' stat over another.
Mahomes is MVPFor argument's sake...based on what? And since Mahomes has only been a starter this past season, limit to an argument as to who was better THIS past season ONLY!
Pretend they were both rookie qb's this year...which was better last season (including playoffs obviously).
Mahomes is MVP
Obviously Brady won it all.
I said Mahomes is better right now
brady fits our scheme loads better than mahomes, so itd have to be brady.Thank you for your answer but let me ask you one more hypothetical for my own clarification. If you were the Titans this year and could replace him with Brady or Mahomes for 2019 ONLY...which would you take to win the Super Bowl this season?

For example, you put the numbers from actual performance in this calculator and the rating is calculated. Coincidentally rating has been figured out historically because it’s based on actual performance.
Rating is not “made up”.
QBR started in 2007, has not been retroactively figured out (maybe because it’s hypothetical and can’t be) but has numbers used in the formula that are not based on actual performance, they are based on averages and situations.
