For example, if William Jackson III signs a 4-yr ext. this week that includes a $12M SB, the signing bonus will be prorated over the maximum allowable 5 years (since you can include the 2020 Cap Year) instead of 4 years, which would lower WJIII's Cap Hits during the 4-ext years.

I don't know if they were allowed to roll over unused cap space back in 2005, but I think that is the reason they gave Carson that big extension.  I think they actually adjusted his '05 salary with unused cap dollars instead of just prorating the signing bonus over a longer period.
