Since 2000, 21 QBs have been drafted in the second round with none drafted in the 2nd in 2000, 2002-2005, 2010, 2015, 2016, 2022 and 2024. The successful 2nd-rounders were drafted at or near the top of the 2nd round in what was then considered to be a deep draft overall or specifically for QBs (Drew Brees, 32 overall in 2001; Andy Dalton, 35th overall in 2011; Derek Carr, 36th overall in 2014). Generally, QBs don't go in the 2nd unless it's a deep draft or they're a high-potential project for a recently-successful team. The former tend to do well (three HOF so far from the 2001 1st round with at least one more expected plus Brees at Round 2, Pick 1; multiple All-Pros) while the latter not so much (John Beck? Drew Stanton?). If you take out the statistical anomaly of 2007-2009, only 14 QBs have been drafted in the 2nd in 22 years. It looked to me like the only position that hasn't had a 2nd-rounder every year.
The outlier is 2007, when three were drafted in the 2nd round in one of the worst QB classes of all time (Jamarcus Russell and Brady Quinn in the 1st; Kevin Kolb, John Beck, Drew Stanton in the 2nd). The Eagles had Donovan McNabb on IR with former 49ers starter Jeff Garcia as the backup and drafted Kolb as the "future" in the 2nd when most had him projected to go in the 3rd/4th and be the 5th or 6th QB off the board. I think the Dolphins have been the biggest offender of drafting 2nd round QBs. The overwhelming majority of 2nd round QBs have been Christian Hackenburgs and Pat Whites who no one could call a sure-fire future starter or who had some question mark that was enough to keep them out of the first round in favor of an immediate or borderline-immediate contributor, but not enough to outweigh whatever buzz surrounded them and drop them to the 3rd or 4th where teams are really drafting players who could sit for a year or more and learn your system.
If Ewers is drafted anywhere in the 2nd other than the first few picks, the odds are in favor of him falling into the latter category. Given his obvious arm talent and decision-making that can be brilliant or puzzling, that's why I put him 3rd-4th. He seems to be the kind of clay a QB guru would want to work with over a year or three.
