please help with 2 CFB spreads

hoping some people here can help.

an organizer of a college football pool requested my help on spread on clemson/colorado and miami/LSU

they seem to be off the board due to klatt (concussion) and russell (shoulder)...

does anyone know what the range of point spreads for these games is? our point spread can be off by 2-3 points but off by 10 points would be terrible.

i have no idea on clemson/colorado other than fairly close... LSU i think would be decent favorite vs. miami (will periloux play in place of russell? i assume not as isn't he redshirting??)
