I don't consider scores prior to 1989 to be relevant in comparing scores. EVERYTHING changed that year with the scores in Wichita and nothing has really been the same since.
Heck, when I rolled 1,900s in 1984-85-86 I was the FIRST IN THE HISTORY OF THE TOURNAMENT to roll three straight 1900s. My teammate Mike Shady has now bowled 14 ABC/USBCs and had 1900 EVERY YEAR!!
Based on the winning scores SINCE 1989, no I don't consider 2,223 out of line.
