Management speak and lying are two different issues. If Cora is stating "well, if the season started today, Carson Smith would be our closer" isn't a lie, because Kimbrel is DTD. However, if the season starts and Kimbrel is the closer, people would see it as "why did he LIE about Smith being the closer"?
If Cora says "I expect Hanley to be our starting 1b" but Hanley gets traded later that day, it doesn't make him a liar. If Cora says "I expect Hanley will be our starting 1b" but Mitch is playing 1b on opening day, it doesn't make him a liar.
