Which of the following bonuses can be forfeited due to conduct or breach?

A roster bonus can be forfeited due to conduct or breach because it is typically tied to the player's presence on the team during a specific timeframe, such as the beginning of the regular season. If a player engages in conduct detrimental to the team or breaches their contract, they may lose the entitlement to the roster bonus as a discipline or consequence for their actions.

In this case, the nature of a roster bonus is such that it can be seen as a reward for commitment and performance, and when that commitment is broken, through negative behavior or failure to adhere to the contract, the team may have grounds to withhold the bonus.

Signing bonuses, incentive bonuses, and playoff bonuses have different structures and conditions attached to them. Signing bonuses, for example, are often guaranteed at the time of signing and less likely to be forfeited based on conduct unless specified in the contract. Incentive bonuses are typically contingent on performance metrics, and playoff bonuses are tied to team success in the postseason, which complicates the rationale for forfeiture based on conduct. Each of these bonuses has its own stipulations and protections which make them less susceptible to forfeiture for conduct-related issues compared to a roster bonus.
