LOS ANGELES (thefutoncritic.com) -- With the broadcast networks scrambling to assemble their 2012-13 season lineups this week, the inevitable question emerges: which nights on which networks need the most help?

Looking back at the current season, here is a list of the 10 nights with the largest year-to-year declines:

-29% - FOX Saturday (1.5 vs. 2.1)
-25% - NBC Tuesday (2.4 vs. 3.2)
-24% - The CW Monday (1.3 vs. 1.7)
-22% - FOX Sunday (3.6 vs. 4.6)
-22% - The CW Friday (0.7 vs. 0.9)
-17% - ABC Monday (2.9 vs. 3.5)
-17% - NBC Saturday (1.0 vs. 1.2)
-16% - CBS Sunday (3.2 vs. 3.8)
-15% - NBC Wednesday (1.7 vs. 2.0)
-15% - The CW Tuesday (1.1 vs. 1.3)

And conversely, here's the 10 nights with the largest year-to-year increases:

+43% - NBC Monday (3.0 vs. 2.1)
+38% - CBS Saturday (1.8 vs. 1.3)
+34% - NBC Sunday (5.1 vs. 3.8)
+20% - FOX Friday (1.8 vs. 1.5)
+18% - ABC Wednesday (3.3 vs. 2.8)
+14% - CBS Monday (4.0 vs. 3.5)
+9% - FOX Tuesday (3.5 vs. 3.2)
+7% - FOX Monday (3.2 vs. 3.0)
+7% - ABC Friday (1.5 vs. 1.4)
+7% - NBC Friday (1.5 vs. 1.4)

So will that mean the biggest changes are to come on the former list with the least on the latter? We'll find out for sure next week.
