I'm pretty sure the cap hit to sign the Rams rookies is $10.24M. At least that's what this article says [
www.turfshowtimes.com] (And they got their info from overthecap.com so I think it's accurate.)
BUT ... only the top 51 players count against the cap. So when the Rams sign their 14 draft picks all the guys from 38th place on down drop off the cap (assuming the rookies will all have a higher cap hit than whoever is/was in 38th place.)
As far as I can tell everyone at the low end of the cap hit list before any of the rookies signed made $750,000. So the 14 guys who get bumped out of the top 51 collectively counted $10.5M against the cap.
Bottom line: the Rams cap space won't change much (if at all) when they sign their rookie class.
