Jamaal was amazing, probably my favorite BYU player of all time. But with how good Allgiere has been, we don’t need Jamaal as much as we need Zach.
Of course, Allgiere benefits from having a much better OL than jamaal ever had, so that’s another variable to consider.
(If we take quality of OL into consideration, then I take Taysom/Jamaal, hands down. Zach/Tyler would get wrecked with the OL that Taysom/Jamaal had.)
