Rising Senior Spotlight - Seth Caslin

Lot of kids work hard on their game, but Millbrook's Seth Caslin takes it to another level. 

Not only did he totally change his body in his first year in the prep ranks but he has continued to find new and creative ways to take his game and body to new levels in the last few months since the coronavirus arrived. 

As a result, he is now being pursued by some of the most elite academic D3 schools in the country - places like Claremont McKenna, Pomona-Pitzer, Brandeis, Vassar, and Wash U - and also starting to ping the D1 radar after recently hearing from schools in the Patriot League. 

Ultimately, his goal is to play his way onto the scholarship level, with D1 conferences like the Patriot, Ivy, or MAAC being an ideal destination.

Personal Statement

My name is Seth Caslin and I will not be outworked. I’m extremely driven, self-motivated, coachable, and I always want to keep growing as a person, student, and player. During the pandemic, I have lived in the weight room and on the court. I have put on twenty pounds of muscle through intense workouts and a strictly regulated diet. I feel confident that my increase in strength and size is going to positively impact every facet of my game, and I’m excited to turn heads.

On the court, I’m a long, 6’4 guard that can play the 1 and the 2 and can score from all three levels. I feel like I have a very high basketball IQ, and I’m a team-first player. On the defensive end, I add length and size at the guard position and grab many rebounds. My key focus in my training this summer is becoming a lockdown defender and elite rebounder for our team next year.


"Seth is a long, athletic young man who is full of upside!  After adjusting to the NEPSAC level of play in the first half of the season, he started to blossom as a scorer, rebounder, and teammate.  Seth is singularly focused on improvement -- both on the court and in the classroom.  He has showed the ability to score with both hands and from three levels.  His bounce and his energy gives him the ability to be a tremendous rebounder, a part of his game that is just coming to the surface.  College coaches -- please reach out, as Seth is the type of student-athlete and young man you want to help make your program better!"  
- Billy Thom, Head Coach, Millbrook School

"Seth is a crafty combo guard that can shoot the lights out. He can score it and get buckets but also play-make and get the players around him better. Since meeting him I've seen that his work ethic is real. He's gained 20 pounds of muscle since being in the pandemic. High academic D1s should get on him early. He will definitely have a major impact his senior year. "
- Doc Kennedy, Head Coach, New Haven Heat

Scouting Report

Caslin is a big lefty guard who shoots the ball very well from the outside. He's a tough shot-maker, off both the catch or the dribble, who provides floor spacing behind the arc and utilizes his size to pull-up over top of smaller guards. He's crafty attacking close-outs, has slippery finishing ability around the rim with both hands, and is capable of scoring at all three levels. His intangibles are also a huge part of his value. His work-ethic is off the charts according to all accounts while his mentality makes those around him better
