The Memphis Grizzlies continue to lock down this year's catches from the NBA draft. Rookie forward Alexander Johnson signed a two year contract Monday. Johnson, who was selected 45th, was acquired via a draft day trade with Portland and Indiana. The Grizzlies picked up 6-9" 240-pound bruiser in hopes of adding some toughness. He played 3 years at Florida State and so far in Summer League games, is averaging 12 points and 9 rebounds.
