Here are the historical first round results:

The #1 seed is 95–1 against the #16 seed (.990). [ugh, don't remind me]
The #2 seed is 96–0 against the #15 seed (1.000).
The #3 seed is 96–0 against the #14 seed (1.000).
The #4 seed is 90–6 against the #13 seed (.938).
The #5 seed is 75-21 against the #12 seed (.781).
The #6 seed is 68–28 against the #11 seed (.708).
The #7 seed is 63-33 against the #10 seed (.656).
The #9 seed is 50–46 against the #8 seed (.521).

So, seeds 1 - 3 don't really get much credit for advancing to the second round.  But a 9 seed beating an 8 seed is a moderately significant accomplishment.

The historical record in second round games is as follows:

Since the expansion to 64 teams in 1994, the following results have occurred for each pairing:

In the 1/16/8/9 bracket:
vs. #8 vs. #9
#1 44–1 (.978) 44–2 (.956)
#16 – 0–1 (.000)
note: The 3 losses by the #1 seed vs #8/9 were: Duke (vs Michigan St, 2009), Ohio St (vs Boston College, 2006), Texas Tech (vs Notre Dame, 1998).

In the 2/15/7/10 bracket:
vs. #7 vs. #10
#2 47–13 (.783) 29–3 (.906)
#15 – –
In the 3/14/6/11 bracket:
vs. #6 vs. #11
#3 45–21 (.682) 16–10 (.615)
#14 – –
In the 4/13/5/12 bracket:
vs. #5 vs. #12
#4 40–26 (.606) 17–3 (.850)
#13 3–3 (.500) –

So, we can figure out how every team performed versus expected.
