This week the Memphis Grizzlies signed a new player, enjoyed their first preseason victory and challenged MJ to a charity game. All in all an interesting week for Grizz Nation.

Memphis signed free agent point guard Andre Barrett. The 31 year-old Bronx native played last season in the NBA Development League. Undrafted in the 2004 NBA Draft, the Seton Hall graduate has played in 67 games (one start) in the NBA over four seasons with six different teams.

The Grizzlies crushed Maccabi Haifa 116-70 in their first preseason win. Granted Maccabi Haifa isn’t an NBA team, but they are from the Israeli Basketball Premier League. Memphis never trailed in the game and Marc Gasol, Tony Allen, and Quincy Pondexter all made their first preseason appearances.

On Twitter, Memphis Grizzlies owner Robert Pera challenged Michael Jordan to a one-on-one charity game for $1 million. Last month, Pera challenged his own player Tony Allen to a one-on-one $100,000 charity game, which was postponed.

Tonight the Grizzlies play the Bucks in Memphis. Hopefully the great depth of their roster, switching starters Conley/Allen/Prince/Randolph/Gasol entirely out for Bayless/Pondexter/Miller/Davis/Koufos, will prove victorious once again for the Grizzlies.
