This post seems misguided on many levels.
1. These guys are all on 10 day contracts, vet min or other extremely cheap deals.
2. The truth is none of them have played enough minutes to pass any definitive judgement on except Crawford.
3. Other than Crawford they are all bodies for insurance, fouls and practice.
4. Semih Erden, Luke Harongody and Flynn? Hard to believe that Ainge passed on such juggernauts of basketball...
5. These guys all have NBA skills, are relatively young and durable with experience playing in the NBA. I can't think of a team with a better end of the bench than the Celtics.
6. Jordan Crawford is putting up fantastic numbers for the amount of money he is earning. He's also playing pretty good defense and seems much better at rebounding than Barbosa.
7. T Will is a project. He has changed his position from a swingman to a point guard. That is why we gave him a contract for next year as well. You should withhold judgment until he gets comfortable with that role.
8. These guys have come into a completely different situation playing in some horrible conditions and inferior talent level in third world conditions (and also we got some guys from china

) to playing for the Celtics. They are also not getting regular time to build up a rhythm. I thought they have done rather well under the circumstance.
I have trouble coming up with how these are "fail pickups." You're not going to get all stars off the free agency on vet min contracts no matter how badly you want to...
