losing a shooter is rarely about the production of the shooter .. but the spacing..
like i noted earlier teams might just crowd the post or play temple in zone.. on paper there is no reason to defend the 3pt line at all with temples current lineup

because temple games had no crowds at all, you could hear opponents screaming "shooter" every time he stepped on the floor... he impacted every game in that way, he gave drivers driving lanes, post players iso (no help) etc..

your projected main guard core for next year-
- battle (31% from 3pt )
- dunn (18% from 3)
- williams (32% from 3 on low volume)
- jahlil white (touted for defense, bad shooter)- no college experience
- hysier miller (low volume shooter in HS)- no college experience

you also lost perry and mooreman, who were shooting bigs.. jourdain percentages are good but too small a sample size to mean anything (just 7 total 3s )..forrester, park, tolbert and okpomo dont shoot 3s at all

without some major addition the formula to beat temple seems very simple
