Probably so. Andy emphasized installing new blitz packages in the Spring. For variius reasons Botts called a read and react D way to often last season. 3-3-5 is not geared for that type of D. My guess he may have had little choice with all the injuries on the back end. Multiple position switches and way too many frosh forced on the field.
This unit has been at rock bottom for years.Botts has to eliminate indecisive play and missed assignments. One positive taleaway from last year is the fact that D did have long stretches of solid play in games. Big plays abd poor tackling negated most of the solud play.
