We think we have good depth and with Scalabrine and Shelden and Glen Davis playing behind the three guys, we have rebounding and we have defense. Big Baby is a very versatile player. Rasheed spreads the floor, and you'll be surprised by Shelden Williams, especially on defense.
This seems like a good time for an executive-level summary of the last four months in Celticdom.
The Celtics ended the 2008-09 NBA season getting thumped by the Orlando Magic in game 7 of the Eastern Confernce Semifinals. A quick look at the box score from that game tells us this:
Doc Rivers could rely on only three players from the second unit, and only one of them was taller than 6-2, Brian Scalabrine. When the 2009-10 NBA season begins, the Boston Celtics will now sport a second unit that boasts three bigs who will likely play in front of Brian Scalabrine, Rasheed Wallace, Glen Davis, and Shelden Williams. If Shelden disappoints (and I really don't think he will, since defense and rebounding are his forte), you have Scalabrine to step in and take his place, and #44 is a decent defender and a threat from range.
So just on this front, we went from a team having three healthy bigs that Doc would use, Kendrick Perkins, Glen Davis, and Brian Scalabrine, to now having twice that many, Kevin Garnett, Rasheed Wallace, Kendrick Perkins, Glen Davis, Shelden Williams, and Brian Scalabrine.
In a sport where adding even one serviceable player to a rotation can make a big difference, I'm not sure we can fully grasp the magnitude of the Celtics' offseason changes this summer, and we haven't even started talking about the addition of swingman Marquis Daniels, the anticipated maturation of Bill Walker, and the depth at our wing positions.
