It's fine. You can interpret "talent" as a mass noun, in which case you wouldn't pluralise it ("There's a lot of talent here.") Alternatively, you could use it in another sense ("He is a great talent," and "Our employees are all great talents.") Interpreting the title in this sense is slightly awkward but certainly grammatical.
