at Football the Terps or pretty good (not great), not to mention they produced some good NFL talent like: Shawne Merriman and Darrius Heyward-Bey, etc.
At Basketball the Terps play in a good ACC Conference, the Lobos are barely mediocre. The only good thing that ever happened for New Mexico is Danny Granger.
As for baseball I have no clue, but I'm guessing Maryland is better than New Mexico.
