I'm all for Rasheed Wallace joining the Cs. He has the qualities that will help the Cs win championship number 18 this coming season, and at least the season after. He's able to provide much needed depth either coming off the bench or starting when needed, at both the four and five spot. Most likely he'll be coming off the bench, except when filling in for an injured or sick [hopefully not ] Garnett and/or Perkins. He has the height and the power, to handle both spots, defensively and offensively can help spread the floor with some three point shooting, when and where needed. There aren't too many high quality power forwards/ centers that have those qualities and abilities that 'Sheed has. What remains is the motivational factor, and considering that Boston has the highest quality starting front line in the NBA, with some of the best motivation coming from that group and the coaches, I foresee 'Sheed as being an important factor in helping the team reach no.18, and more.
Should Grant Hill consent to playing for Boston this coming season, I can only see that as a positive. As long as Hill is healthy, he's one of the more talented players in the NBA, who would do a great job of helping to minimize some of P.P.'s minutes, which would help P.P. maximixe his on floor time.
Should they both sign on with the Cs, I believe that Ainge and co., will continue to add some additional bodies who are capable, to the bench, as they realize that quality help is needed. 'Sheed and [ hopefully ] Hill make a great start to the off season wheeling and dealing.
