The thing is, people use stats and don't understand them all the time.
Only 5 QBs had winning records versus teams over .500. That tells you how hard it is to do.
QB's record is their record. Their entire record, not some weird sub-divided thing used to drag a guy down.
I will say Romo had a lot of years to break through much like Garrett and did not.
All his fault? Absolutely not.
But pretending he would somehow have the magic formula to winning playoff games now is bizarre.
He was 2-4 in the playoffs for his entire career.
