TJ back problems are legit and the decision to extend his contract was a major issue for the Bucks.

I guess while healthy they felt they could make a decent trade for him now than risk having a defective player whose contract likely has insurance restrictions (not cover his chronic degenerative stenosis condtion)which could inhibit a fiscally sensitive ownership structure in a small market.

Bucks have upped the bar lateley and still have a nice team. With the increased financial commitments they took on its actually a conservitive play that won't hurt them.

TJ is a risk for the Raptors That could pay off very well for them. A typical "risk/reward" type trade whose results can be evaluated for years.

A Stenois of the spine is a narrowing of the discs.

Isiah like to trade for players who have big contracts and have "Cranal Stenosis" which is a narrowing of the mind.
