Not sure how to convert a spread to a ML since it is likely model and sport specific and could be game specific too. Will use the UK game to show some of the lines in either direction from the base spread/ML (-36.5/-110).
-33.5 = -162
-34.5 = -144
-35.5 = -129
-36.5 = -110
-37.5 = -103
-38.5 =...
On most betting apps you can. For example, Draft Kings has UK at -35.5 (-110) vs Bellarmine. You have the option to move that from -23.5 (-535) to -47.5 (+304). Buddy of mine did a parlay last night with one of the legs being Heels -32.
