I think NCAA rules committee will need to re-evaluate rule on substitution this off-season. Our fast-paced offense has taken advantage of the defense’s inability to make substitutions if offense doesn’t make substitutions. However, the problem is when offense does sub and ref stands over ball and allows defense to sub, while clock is winding down. Defenses are now slow walking onto field to allow play clock to wind down. This sometimes requires offense to take timeout. I know Tennessee has been guilty of this strategy on defense. Doesn’t seem fair to offense IMO.
