Dynasty fantasy managers need to make tough decisions about their tight ends this offseason, particularly with a group of aging and underperforming players. David Njoku of the Cleveland Browns, despite a resurgence, is a player to consider moving due to contract uncertainty. Cade Otton's breakout season may not translate into sustained success, and he should be sold if better options are at hand. Jonnu Smith’s career year in Miami is enticing, but his age makes him a risky investment. Dallas Goedert's injury history raises red flags, suggesting it's time to cash out. Lastly, Zach Ertz's late-career revival presents a sell-high opportunity, but his future remains uncertain.
