By his third year, Allen had thrown for over 4000 yards, 28 tds and came off the bench to lead Edmonton to a Grey Cup win and was GC MOP. Calvillo has almost 8000 passing yards and 45 tds in his first three years. Shaky both may have been but they showed far more than Davis.
Good comparison perhaps but I'd risk Durant over Davis/Lefevour. I mean in a perfect world our scouts find a new to the CFL quality backup who can grow into a starting QB but that has not happened in Winnipeg since 1990.
