First, Furman has occasionally had a backlog. Furman took both PJ Blazejowski and Harris Roberts in the same recruiting class, for instance. That was a year after taking Dillon Woodruff (who would eventually play linebacker) and two years after Reese Hannon (who lost a year to injury). Hannon played most of his four years, leaving Blazejowski to start as a senior full time and then Roberts as a 5th year senior the next year. Furman will begin 2019 with its fourth straight different starting QB in four years.
I think Furman wants to get back to a spot where there is more space in that position. Ideally, it would have been nice to have Hannon turn the reigns over to Blazejowski in his junior season, who then would turn it over to Roberts in his junior season.
Let those guys spend a few years in the program, get used to the offense, and then spend two years as the starter.
