if he advances too quickly he might start getting offers much more lucrative than whan the Spurs can offer him as the 28th pick...
Something I didn't know about the new CBA is that it allows for a huge increase (compared to the last CBA) in salary for low first round draft picks in his fourth year--over 80% in Ian's case. If the Spurs opted to pay Ian the most they could according to the rookie scale his deal would look like this:
Code:
1) 874,080
2) 939,600
3) 1,005,120
4) 1,814,241.60
Total: $4,633,041.60
Then even if he only takes the qualifying offer of $2,721,362.40 the following summer he's looking at $7,354,404 over five years, about $1.47 million a year.
After looking at that, I'm not worried about Ian's indenturing himself to a European team with a long term contract. It's in his (and his agent's) best interest to start the clock on his rookie deal ASAP, so he can get that big payday after the initial $4-4.6 million.
