Richard Cohen, who follows contracts on a pretty thorough basis, wrote about the flurry of waivers last week and subsequent pick-ups this week.
"The league has reduced the waiver period around the midpoint to 24 hours this year, so the deadline to cut players in order for them to clear waivers in time is Friday, June 24, at 5 p.m. ET. Expect to see at least a few moves around the league as teams release players on the end of their benches to open up salary cap space and roster spots to try players out on seven-day contracts instead. Or just to avoid committing themselves to money for players that they don't think are worth it."
I suspect Evina and others in her position from here on it will be signed to 7-day contracts and hope to just keep renewing them.
BTW, Cohen thinks that Crystal could be resigned closer to July 4th after missing one game for the Liberty (if she is indeed resigned).
Stay tuned.
BTW, Evina is getting bounced around this year, but I remember Megan Gustafsson doing the same for a season (or two). What helped her? Getting reps in games overseas. Knock on wood for her, Gustafsson has stuck with Phoenix this season.
