The RPI is not the only way to judge. Their advanced metrics sucked, and they had bad losses...a couple of them.
Their advanced metrics were all in the tank, just like this year, and they had one win to hang their hat on: Kansas. A big win, mind you, but look at the actual substance of their record and it made sense they weren't in.
They were the next team out? Fair enough. When you get that deep into the bubble all teams look pretty bad upon closer inspection. I just think people didn't look close enough at Temple to realize how precarious their situation was.
I think the narrative that the AAC is treated unfavorably the committee is overstated on this board, but the metrics you cite in this post are the same ones that weren't used the year prior, and the traditional data points that were used in 2014 were de-emphasized last season when it was time to justify the inclusion of a brand program like UCLA.
Comparing the resumes of SMU and N.C. State in 2014, it isn't outrageous to argue that the goalposts are being moved to satisfy some subjective inclinations:
SMU - 3-4 vs. RPI top 25, 4-5 vs. RPI top 50, 4-6 vs. RPI top 100, 53 RPI overall, 31 BPI
N.C. State - 1-7 vs. RPI top 25, 3-9 vs. RPI top 50, 6-12 vs. RPI top 100, 54 RPI overall, 61 BPI
By virtually all objective data, SMU was more tournament worthy than N.C. State. Did it help N.C. State that they were in a power five conference? Did it help them to have rich program history and a large, traveling fan base? Did it help them to have one of the best players in the country in T.J. Warren?
To infer that extraneous variables may contribute to the selection process does not insinuate that there is corruption. If the advanced metrics are going to be presented in opposition of last years Temple team, then it is a certainty that by the same logic there were three AAC teams shafted in 2014.
Cincinnati was seeded properly in 2014. I think Memphis was, as well. SMU and Cincinnati both got fair shakes last season, and Temple - taken by some criteria - was hardly an egregious omission. In examining all of the data, though, it's fair to wonder whether the tie actually goes to the runner if you're from this conference.
