In late April, Keller skated for the New England Nordiques in the World Selects Invitational in Saco, Maine, earning kudos from U.S. Hockey Report:
Clayton Keller, F, ’98 (New England Nordiques) 5-8/150 — We saw the Shattuck-St. Mary’s forward at Nationals a couple of weeks ago, and wrote that he reminded us of Zach Parise at the same age. We’ll stick with that. The Bellville, Ill. native is an effortless skater with a top-notch skill set. Makes plays every time he touches the puck. Is only going to get better when he begins to fill out. Our only knock on him is that we would like to see him add some more finish to his game — he’s definitely a ‘pass first’ player. Regardless, we’re convinced Keller is a young star in the making.
It's a huge pick-up for the Terriers and new head coach David Quinn, in an area that BU isn't necessarily known for recruiting from. Keller is just entering the 10th grade this year, so he wouldn't join the Terriers until 2016 at the earliest, but it's a very positive sign for BU's long-term stability to lock up quality players like this.

A Shattuck U-14 product was the best player on the ice on Saturday. He is on the small side but competes for every puck. He has high-end skills and is very slick and creative with the puck. His game on Saturday made him the #7 best forward at the camp in AHR’s opinion. AHR Rating: A

Keller boasts a whopping 13 points in 5 games in the HPHL and has an outstanding wrist shot. He is a power play specialist with a good set of hands to boot. When you first see him on the ice you wouldn't expect it because he has an awkward stride and has room to grow, but as soon as the puck drops it is pure domination from there. If he brings his footwork up to speed he should be a top tier prospect for years to come. Your typical SSM stud. AHR Rating: A
