with 2-2 not out of the realm of possibility. Going 0-4 is certainly a possibility as well, but 1-3 seems by many to be the "most likely" outcome according to many. Even if they have us a "underdogs" in all 4 games, we have enough of a chance of winning that the expectation is pulling off at least 1 win in the group. For example, FPI gives us the following probabilities of winning each of our first 4 games:
vs Utah 39.5%
@ Tenn 18.6%
vs USC 45.4%
vs Wash 35.8%

We'd be underdogs in each of those 4 w/ USC close to a toss-up. The "expected" number of wins in the first 4 would be 1.39 wins meaning they would expect us to go 1-3, but 2-2 is more likely than going 0-4. Here's the odds breakdown of each record possibility:

0-4: 17.5%
1-3: 39.2%
2-2: 31.5%
3-1: 10.6%
4-0: 1.2%
