The 3A West region is going to look very different in 2017. Five schools are out - four of them moving down to 2A, one (Urbana moving up to 4A). With them go some of the top teams and individuals from 2016: Poolesville's Ryan Lockett and Nandini Satsangi, this past year's champions, are the most notable. The Poolesville boys and girls also won in 2016, meaning there will be four new champions next season. Oakdale, Damascus and Urbana also finished among the top five girls' teams and Oakdale and Urbana in the top five on the boys' side, so the remaining teams will find more opportunities to make it to states.
Replacing them will be four Montgomery County schools coming in from the 3A South region: Magruder, Blake, Rockville and Watkins Mill. They don't figure to be quite as strong as the teams moving out so this region may be a bit weaker overall than it was in 2016. Another interesting note: Watkins Mill hosted the 3A South regionals for the past two seasons, and with the 2016 3A West host Urbana moving out, the meet could shift back to Watkins Mill.
