Drew Brees? He didn't break out until year 4, but he only played 1 game year 1 and 11 year 3, so "game wise" he was in the 3 year window. Took until NO to really ascend and get more consistent, but he was top 3 in Passer rating that year (single, flawed stat, all that it is, but still) Meeting Sean Payton was the best thing to happen to Drew Brees.
