Men’s basketball head coach Tommy Amaker is inviting several highly sought-after recruits to Cambridge for their official visits this weekend, which coincides with the football team’s home opener. Last year, Amaker hosted a similarly talented group but failed to secure the top prospects. This year’s visitors includes Californians Kenyatta Smith and Spencer Dinwiddie, Memphis guard Andre Hollins, and Cameroonian Steve Moundou-Missi.
