Most QBs numbers today are better than QBs from nearly 20 years ago....duh. In 2002 only 4 QBs passed for over 4,000 yards, the most TDs thrown were 28, only 4 QBs had a rating over 90, and 13 starting QBs threw 15 or more INTs. In 2003, there were 2 4,000 yard passers, most TDs thrown were 32, 6 QBs had a rating over 90, 13 QBs threw 15 or more INTs. 2004 was a weird outlier year, 5 QBs threw for 4,000 or more yards, most TDs thrown was 49 (Manning), 11 QBs had a rating over 90 (Including Drew Brees), 11 QBs threw 15 or more INTs. In 2005 8 QBs had a rating over 90, most TDs thrown were 32, 2 QBs threw for more than 4,000 yards, INTs were still incredibly high. In 2019, 14 QBs had a rating over 90, 11 QBs threw for 4,000 yards or more with one being over 5,000 yards, 6 QBs had 15 or more INTs.
NFL rules have made the game easier for QBs.
