I'm paying a bit more attention to the summer league this year, having done no more than check the box scores/highlights for my team (Rockets) in previous years, and I noticed something that I thought someone here might be able to confirm or disconfirm:

I've always thought the summer league is tailor made for (1) giving first round draftees that will eventually be rotation players a first look at the team's sets & NBA-style competition and (2) getting a look at undrafted or 2nd round players and determining if they deserve a contract.  This year, however, the latter seem to have been pushed out a bit because several teams are playing 2nd and 3rd year guys who were in the rotation last year (like Beaubois, DeRozan, Lawson, and half the Rockets team).

Is it just me, or are there many more minutes going to guys who already have both NBA experience AND a guaranteed spot on the team?  If so, why?  Are teams cutting costs by scouting fewer players?  Is there a trend toward developing young guys in summer league instead of or in addition to training camp?  Am I just reading too much into having experienced players dance around the summer league for a few games?
