Simply put, Ainge needs to gamble, as proven commodities are out of the team's price range for the most part.
One can gamble that aging veterans in decline will have a mini-renaissance for a season. I am not in favor of this gamble.
One can gamble that talented, injury-prone players will be healthy. I am wary of this gamble.
One can gamble on unproven talent. This is the type of gambling I prefer.
This is how I feel about it. There are some young bigs who are going to be free agents this year who could likely be signed pretty cheaply so the gamble's not too high.
Kris Humphries, Josh McRoberts, Solomon Jones, Hilton Armstrong, Alexis Ajinca, Hamed Haddadi, Jason Smith, Joey Dorsey, Yi Yianlian, Kyrylo Fesenko, Ryan Hollins, and Jonas Jerebko are among the lesser known, younger 4s or 5s on the market. Not splashy names, but I'm all for Danny continuing the pattern of starting the season with a young, cheap big who can chew some minutes, and maybe eventually we'll get one who sticks for the long haul.
