<p>From a contract perspective, this is probably straightforward:</p>
<p>Coach makes an offer, contingent upon counterparty (the student) taking a specific action by November. She did not sign, so there was no acceptance and no contract, only an offer. The offer was withdrawn before an acceptance could occur.</p>
