The Pending Offers screen (League Menu >> Transactions section >> Available Personnel >> Pending Offers tab) is where general managers come to review pending contract offers to team personnel:

Each offer that you have made displays here until the offer is resolved (accepted or finally rejected). The Reaction column will tell you how the player feels about your current offer. If the player has responded negatively, such as that he wants more money, just right-click on the person and select Offer Contract, and offer him something better!

If you have changed your mind about offering a person a contract, click the Withdraw button to withdraw an offer. Offers that other teams have made are not displayed here.

See Coaches and Personnel for more information on team personnel.
