So, how’d last game go?

Expectations were not overly high heading in to this game, as Nashville has not been a friendly venue for the Tide in recent years, not to mention the rash of injuries that looked to have Alabama down three players from the mid-season rotation. So, naturally, the Tide came out in the first half and really took it to Vanderbilt, bouncing back from a rough start to drop 22 points in the final 8 minutes of the frame. They even got 15 minutes out of presumed no-go Michael Kessens[1], who was questionable with a bum knee. Jimmie Taylor was a factor early and often. Levi Randolph was producing before the last 5 minutes of the game. The offense was humming on all cylinders. A Retin Obasohan three-pointer with 17 seconds left made it a 14 point margin, but a Wade Baldwin IV three-pointer cut the lead to 11 right at the half, producing a 38-27 score heading into the locker room. All was right with the world.

1 | For the whole game, that is.

That is, until after the break. In contrast to previous games, where the Tide pissed away the first half only to make things interesting in the second, ‘Bama came out of the locker room completely flat, allowing a 20-3 run for Vanderbilt to start the frame. In addition to going ice-cold from the floor, the foul attempts ramped up in favor of the Commodores, who went 18-21 from the line in the half. The Tide managed to shoot well from the line at 80%, but on just 10 attempts. The margin never closed to within 4 down the stretch, and Vandy took home a 73-66 victory. Few among the crimson faithful were anticipating a win in this venue, but they certainly were not expecting this team to find a new, exciting way to lose at this stage of the season.

The Four Factors

The Four Factors
eFG% 50.0% 52.0%
TO% 18.3% 15.0%
OR% 45.5% 33.3%
FTR 17.2% 49.0%
Win Index 43 47

The Tide shot pretty well in this one at 50% eFG%, but Vanderbilt shot just a little bit better. The Tide took pretty good care of the ball at a TO% of just 18.3%, but Vandy took care of the ball just a little bit better. The Tide actually won OR% despite a significant size advantage inside for the Commodores. Unsurprisingly, the bugaboo was at the line, where Vandy had a 25-10 attempt advantage for the game. I was not able to watch the second half at all this week and as such can’t comment on the officiating, but I find it odd that the Commodores were able to accrue so many attempts during the frame after starting from such a deep hole. Curious.

Wait, aren’t you supposed to be previewing something, nerd?

So, what do we know?

BPI is a bit higher on Ole Miss than PYTH, but in both cases they are much lower on the Tide, with each advanced metric pegging the good guys at #59 overall. Neither of these teams have impressive-looking win-loss records, and as such RPI is cool on both of them. Shockingly enough, the Tide are thoroughly on the “underperforming expectation” side of the aisle, which may have something to do with a slew of injuries those for which those expectations do not account. Ole Miss is in the same boat, and actually to a worse degree than the Tide.

UPDATE: Nefarious spreadsheet betrayal lead to the above comments regarding Ole Miss' RPI rating. It's been fixed.

Ole Miss’ profile is very similar to Vanderbilt’s, in that they are a good offensive team that isn’t particularly effective on the defensive side of the ball. Unfortunately for Tide fans, Ole Miss isn’t just good when they have the ball, they’re lethal, currently rating out 19th overall in OE+. They can, and have, scored points on everybody, including dropping 86 on Kentucky[2]. Ole Miss doesn’t bring an interior matchup nightmare of the Damian Jones / Jordan Mickey variety, but they do have capable three-point shooters in guards Stefan Moody and Ladarius White, and Moody is effective from the stripe at 91.2%. Despite the Tide’s capabilities on defense, expect for the Rebels to put up a ton of points.

2 | Albeit in OT, in a game Kentucky probably wasn’t taking seriously to start.

The key will be whether or not the Tide can keep pace with Ole Miss’ scoring. The Rebels are atrocious on the defensive side of the ball at 111th in DE+, which seems like the perfect panacea for the Tide’s offensive woes. While that was true for a half against the similarly-challenged Commodores, the Tide’s streaky shooting showed up again to tip the scales out of their favor. This is the kind of game where the scoring abilities of Ricky Tarrant are missed the most, as the Tide offense ran in a different gear when he was sharing the backcourt with Randolph.

Alabama has faced the tougher schedule than Ole Miss, but not by much, and that’s mainly the second Kentucky game at work. The magic box has this at 60.3% for the Tide when accounting for the venue at Coleman, but given the uneven attendance as of late and generally flagging interest in Tide basketball at this point in the season, I’m not overly optimistic about the home-court advantage. The neutral-court win expectancy for the Tide is a less-rosy 44.4%, which is the more accurate number for this one I’m afraid.

THE PICK: Ole Miss Rebels
