An interesting comparison---> the RPI and the PSR   Message List  
Reply | Forward Message #1665 of 2118 |
As this poster's previous message has clearly conveyed, your humble
servant is VERY unhappy with the RPI formula--- it seems very heavily
skewed in favo(u)r of the teams from the 6 so-called B(C)S
conferences. By contrast, the PSR ratings seem more objective or
disinterested (in the proper sense of the word, meaning impartial).
Mr. P.'s math treats all teams more equally. Thus, it seems like an
interesting exercise to compare teams' RPI and PSR ratings, and
compile two lists, one list of those teams who seem to benefit from
an inflated RPI, and the other list of those teams whose RPI appears
to be artificially low. Is anyone math-savvy (and a glutton for
punishment) enough to compile said lists? Could Mr.Palm be persuaded
to render this public service? (^-_-^)

At a cursory glance, one gets the impression that being part of the 6
BCS conference gang IS an advantage, particularly for a team with a
large number of losses. Methinks losses should be penalized, but the
RPI doesn't seem to think so, or at least not enough.^^ One notes,
for example, Clemson, 9W-13L, at -14 (PSR of 81, RPI of 67),
Alabama ,12W-9L, at -13 (PSR of 37, RPI of 24), Missouri, 11W-10L,
at -14 (PSR of 61, RPI of 47), California, 11W-10L, at a whopping -26
(PSR 96, RPI 70), Auburn, 12W-9L, -14 (PSR 78, RPI 64), and UCLA, 10W-
11L, at -22 (PSR 124, RPI 102). If Canadianbucko were on the
committee, there's no way he'd vote for ANY of those teams--- their W-
L ratios are WAY too poor--- but unfortunately the status quo will
prevail, so one of either Alabama or Auburn, or maybe both, will get
to go "dancing". Maybe even Clemson--- Yuck!

On the other hand, it appears that some teams from the "great
unwashed" conferences (i.e., non-BCS) are penalized in spite of doing
what should be the most important thing---> namely, winning. One
notes 20W-2L Utah St. at +15 (PSR 24, RPI 39), 20W-2L Southern
Illinois at +12 (PSR 11, RPI 23), 17W-3L Kent St. at +19 (PSR 44, RPI
63), 18W-3L Western Michigan also at +19 (PSR 40, RPI 59), 18W-4L UCF
at +33 (PSR 49, RPI 82), 22W-4L East Tenn.St at +20 (PSR 63, RPI 83),
18W-4L Creighton at +18 (PSR 54, RPI 72), 19W-4L Boston U. at +24
(PSR 68, RPI 92), and 17W-5L Coll. of Charleston at +38 (PSR 79, RPI
117). These teams have taken the mantra "Just win, baby" to heart,
but alas for many of them that won't be good enough. This appears to
this observer to be flawed, unfair, and simply incorrect...
