Sam Brown Jr. NFL Draft 2025 Scouting Report for Miami Dolphins WR

The Miami Dolphins added University of Miami (FL) WR Sam Brown Jr. as an undrafted free agent after the 2025 NFL draft.
Sam Brown Jr. is a long-legged strider with field-stretching speed to take the top off the defense.
Brown is an explosive, raw athlete. He stresses defenses vertically, especially if left unattended or uncovered at the line. He opens his long stride and glides past coverage defenders with their eyes in the backfield. He possesses the athleticism to be a weapon down the field off play action.

Brown flashes good football IQ against zone defenses, where he finds open space and works into the creases confidently. Brown is a smooth route-runner with fairly good hips to sink at the top of his routes. He snaps off quick hitches and comeback routes with good timing and readiness for the throw. Brown is a physical route-runner. If the corner is grabby, he will fight through the contact effectively.
For a receiver with his athletic ability and NFL size, Brown’s touchdown production is minimal. Only nine receiving touchdowns in five collegiate seasons is hard to understand.
Brown is not as sure-handed as some teams would prefer. He averaged four drops in three straight seasons. He needs to expand his release package against press-man alignment. He lacks the creativity to keep corners on their toes. He needs to develop answers for long-limbed and athletic perimeter defenders in the NFL.
Overall, Brown projects to be a WR4/5 with the physical tools and size to warrant a chance to compete for growth during training camp and the preseason. If he can eliminate his repetitive release package and become more reliable in contested-catch situations, he should have a chance to make a 53-man roster.
