Another way of looking at it:

Steve Smith posted his first multi-TD game since Cam Newton's debut (2011). Smith has as many multi-TD games with Joe Flacco as he had in three years with Newton. - ESPN NFL Power Rankings, week 5

Or: it took Smith four times as many games to get his first multi-TD game with Flacco as it took with Newton. As it happens, I think Flacco is the better QB, but still.
