The reads behind them

College props on this site are read on form and the matchup, not on price. A prop appears when the player has cleared the line in at least 60% of his games across this season and last, at least two books quote it, and the matchup does not argue against it. The price is the best among the books quoting the line, with the next best named beside it. Early in a season the samples are small, and each read says how small.

What this is, and what it is not

These are our strongest props in this matchup, chosen on how often the player has cleared the line across a small sample, the matchup itself, and the best price among the books quoting it.
