Boys Sprint Relay
4x200m
You've got four teams with season bests at 1:33-point, which is setting up a loaded final. The major players are Central, NJ, Roman Catholic, PA, Wise, MD, & Teaneck, NJ, in that order. A little bit of flavor from everywhere around the East Coast.
4x400m
There has yet to be a strong performance by the teams listed, although it would seem Wise, MD has the pieces to put something together. US #2 St. Peter's for the 4x800m is dropping down in distance, and could string something together that's competitive.
