Welcome to Friday Figures, a new weekly column where we’ll look at some interesting statistics from around the Big 12. There will be charts, graphs and plenty of references to KenPom. Obviously it’s still early, so this week we’re going to dive into a trio of numbers worth tracking as the season progresses.
West Virginia’s true shooting attempts differential always looms large. Under the “Press Virginia” system, the Mountaineers’ offense has never been the most efficient from a shot-making perspective. Dating back to the 2014-15 season, West Virginia has ranked 292nd, 177th and 139th nationally in effective field goal percentage (per KenPom). So far this season, they rank 185th. But what West Virginia lacks in accuracy, it makes up for in sheer volume by creating extra shots with offensive rebounds and opponents’ turnovers. Last season, the gap between the Mountaineers’ true shooting attempts (TSAs), a formula which accounts for free throws as well as field goal attempts, and their opponents’ attempts, was the largest in the country at 11.3 per game.

Tracking that differential in TSAs on a game-by-game basis has been a pretty good way to figure out West Virginia’s chances of winning. The chart above plots every game the team has played since 2014-15 with losses marked in red. Notice how the presence of that color increases significantly when the differential falls below 10.0? In two games so far this season, the Mountaineers have experienced wildly different results. Against Texas A&M, they only took 1.2 more TSAs than the Aggies, but in a blowout win against American, that gap was 25.4. One was a 23-point loss while the other a 34-point win. If you’re tracking West Virginia’s box scores this season, simply observe the gap in field goal attempts and free throws versus the opponent and you will likely be able to figure out how the game is going.
