Someone who knows more about salary cap than me  - please explain.
 
	If this is a one year rental. And we can roll over cap space to next year.
 
	Then we have 6 mill less in cap space next year when we may want to upgrade that o line with a free agent.
 
	right? i have never properly understood the cap rollover rules.
 
	if you can roll over cap space - why ever do a rental - unless you are gunning for the SB?
 
	please help-
