USC's Su'a Cravens -- Gettin' Mom a Baller Gift ... When I Get Drafted (VIDEO)

Su'a Cravens is about to be a wealthy man ... he's expected to be a top pick at the NFL Draft ... and he's already planned on how he'll spend his first paycheck -- on his mom.

Some draft analysts say the former USC linebacker could be a 1st round pick on April 28th ... but Cravens didn't seem to be letting the pressure get to him during a shopping trip in L.A. Thursday.

In fact, the guy told us he's already thinking about how to make money outside of football by using his (gasp) college education! Pretty cool, right?

So, what's Su'a gonna get his mom with all that cash he'll bring in??
