Food for thought regarding jayharvill's question: At this point, Lebron's got 7 really, REALLY good seasons and will have an 8th well before we get to season 8. Probably even a 9th one.
I actually drafted Lebron in the 1st round of the previous version, which was right after the 07-08 season. Had the 09-10 seasons been released on time, this season would have been his 09-10 season for me, and I would have been heavily favored.
Sooo... yeah. Guys that play long are at a premium... but guys that play at a high level for a few years are too.
