Seriously "why does it matter?"
it matters because the intention was to not offer anything or how you phrased it "to see how the injury progresses." Boston only offered to match clevelands offer to save face.
I don't think it was to save face. I think they wanted him back. I just don't think they believed anyone else was willing to offer him a contract until he was closer to returning.
The C's paid for his surgery and recovery, let him use the facility, they just were not willing to bid against themselves to pay him when he was nowhere close to play basketball.
Thing is that the offer Powe accepted, 1 year deal with a team option, was never something that he allowed the Celtics to pursue. Powe wanted at the very least a one year contract from somewhere, so he could be a free-agent the following year. Celtics were going to wait and see on those conditions, Powe didn't find anyone who wanted to give him that type of contract, he then went to our rivals, and accepted a one year deal with a team option (which I thought was dumb for him to accept) and when the Celtics saw that Powe might actually go for that type of deal, matched it but Powe refused. I'm willing to bet that a two year contract with a team option the Celtics would've done so in a heart beat if it was on the table from Powe's camp from the get go, but Powe didn't want that, and settled when he couldn't find what he wanted.
So the thing in all of this is that Powe was unwilling to level the playing field with the Celtics. The Celtics, and rightfully so, were being cautious about offering him the one year contract particularly when by doing so, they would lose their restricted free-agency status on their dime. Then you add to that that even before the injury, all speculations were that Ainge would have to choose between Baby and Powe in that free-agency year, that keeping them both was not in our best interest. Add to that KG recuperating from his injuries, limited roster spaces, and very thin big men depth.
Now, I can't blame Powe for going elsewhere looking for a contract, particularly since he was injured and needed to make a living. Still, if Powe wanted to be a Celtic he would've been, that's the bottom line regardless of when the offers were made.
