Ex-NBA player Chris Carr is one proud dad ... telling TMZ Sports he's thrilled to see his son follow in his pro hoops footsteps and get drafted to the Los Angeles Lakers!! We caught up with the former Suns and Timberwolves shooting guard at LAX on Friday ... and he's still over the moon after 21-year-old Cameron -- a standout at Baylor -- went No. 24 in Tuesday's draft. Carr loves how Cameron is joining such a historic franchise ... but now that he's got his NBA home, it's time to get to work.
