How this game plays

what the study found each side's numbers actually do when these two teams meet
AdvantageS Illinois
Where S Illinois struggles: shooting
S Illinois shoots an effective 49.2% (#286); Portland St allows 48.8% (#56). Expect about 48.8%, 2.5 points below an average D1 matchup — worth roughly -3.6 points per 100 possessions.
AdvantagePortland St
Where Portland St struggles: shooting
Portland St shoots an effective 50.6% (#211); S Illinois allows 49.0% (#70). Expect about 49.7%, 1.6 points below an average D1 matchup — worth roughly -2.2 points per 100 possessions.
Watch for noise
3-point caution
A notable season 3-point number here (S Illinois, S Illinois's defense) is close to a coin flip going forward — the study's model of next-game 3P% barely beats guessing the D1 average. Shot volume is what actually carries: expect Portland St at about 36.8% of its shots from three, S Illinois about 31.4%.

Head-to-head

this season and last
No meetings the last two seasons.

The CBB Matchups tab lays out the day's Division I slate: matchup, tip time, records and rank, and — once posted — Pinnacle's spread and total (the median across books when Pinnacle has no line). Three views switch the table between projected scores, pace and totals, and each team's offensive and defensive tendencies. Each game opens into opponent-adjusted possessions, efficiency and four-factor tendencies for both teams, plus recent form, rotation and head-to-head history. Every game also carries our projected score, spread and total, built bottom-up from those same numbers: expected possessions times each side's opponent-adjusted points per possession, plus home court.

What these numbers mean: line shopping.
