Dynasty fantasy football leagues are back in full swing, and the key to building a great dynasty team is finding young stars before they break out. These are some of the top dynasty sleepers who you should buy low on before they break out this season.

RB Nicholas Singleton, Tennessee Titans

Singleton has an impressive combination of size and speed, and landed in Tennessee, where he could see a significant role faster than many fantasy owners may be projecting. Tony Pollard is a solid running back, but he's also 29 years old and on an expiring contract. Tyjae Spears has not worked out at all, as he's struggled with his health and hasn't been special when on the field.

We could see Singleton get an opportunity this season, and potentially enter 2027 as the clear-cut starter. He's an explosive back with the size to drag defenders along with him. With two 1,000-yard seasons and 54 touchdowns (45 rushing, nine receiving) under his belt in four years at Penn State, he is a high-upside rusher; however, he's also an excellent pass-catcher. If you can acquire Singleton, you could be getting a 2027 bell-cow option.
