I'm wishing they would have second session of summer league, or even move the July league up a bit. There's just so much dead space right now, almost unbearable.
The Big 3 has their Championship this next Saturday I believe. Joe Johnson is owning that league. His team is in the finals. It has helped. That and I like the Mercury.
Summer League should be in August before preseason. It would help the guys looking to make rosters also. They could get in shape for SL and then they're on to preseason a week or two later. Everyone is more familiar with one another and focused on the season ahead. Free agency and the draft is enough to occupy everyone in late June and early July.
If they held off on Summer League any later in the year then they'd lose a ton of their prospects to foreign leagues, hell, I wouldn't be surprised if some 2nd rounders decided not to chance it and went after guaranteed money overseas.
The vets could still take August off. It would be the fringe players that would need to show up for SL and I doubt those guys rest like others anyway because they played SL in July and have to wait about 2 months for training camp to roll around and hope to carry over their SL success to get a real roster spot. I would guess that those who impress in SL play and get camp invites spend 2 months doing whatever they can to be ready to earn a real payday when training camp starts. This would allow them to prepare once, for SL and then camp because there would be a short break between the 2.
