Posted by BRIGGS:
the rule is pretty easy to interpret, You CANNOT trade 1st round picks in consecutive years UNLESS you have an additional pick in the 1st round for that year. since Houston traded away their 2004 pick, and subsuquently have no additional 1st rounder for 2005, they are obligated to make that pick. they can trade it right after they make it, but nonetheless they cant trade it beforehand.
Briggs...read the statement again....specifically:
For example, if this is the 99-00 season, then
teams can trade their 2000 first round pick without regard to whether they had a 1999 pick, since their 1999 pick is no longer a future pick. But they can't trade away both their 2000 and 2001 picks, since both are future picks. Teams sometimes work around this rule by trading first round picks in alternate years.
