Regarding the second stall call on Arnold, this is what the 2025-26 and 2026-27 NCAA Men's Wrestling Casebook says regarding when to call stalling in a kickout situation at the OOB line:
"A.R. 5-17. Is it a mandatory stall call when a wrestler kicks out from a lower leg hold? RULING: No. A wrestler who stays in bounds while kicking out of a lower leg hold in either the neutral or down position, should not be called for stalling unless the referee believes Rule 5.7.1 (avoiding wrestling as an offensive or defensive strategy) applies.
If, however, a kick out by a wrestler results in an out of bounds call being made by the referee, then the wrestler kicking out shall be called for stalling (Rule 5.7.8)" (emphasis mine)
My question is if Arnold's kickout actually pulled Ryder out of bounds? Unfortunately the footage angle doesn't show Ryder's foot that is nearest the OOB line. My assumption would be that if Arnold's kickout pulled Ryder out of bounds then a stalling call would be warranted per the above, but if Ryder stepped out of bounds on his own then no stall call would be warranted.
And for those who are not aware what the NCAA Wrestling Casebook is, it gives various and numerous (42 pages) examples of wrestling and officiating scenarios, and how to properly handle them. It is an excellent resource for referees, wrestling officials and us wrestling fans who enjoy learning the intricacies of wrestling officiating. Here is the link:
