Carson Beck passed every test in NFL debut, here's why history says it doesn't matter

However, CBS Sports notes that recent history with rookie quarterbacks shows preseason performances can be highly misleading indicators of future success. The report cautions against reading too much into Beck's strong showing, citing precedents of other rookie quarterbacks whose preseason results did not translate to the regular season.
