team and season.

I'm not convinced this is a "now or never" year for Tech (though Tech graduates a number of key pieces, most notably Robinson and Clark), but I do agree with the article's conclusion:

"[W]e think that there's enough offense and veteran presence (four seniors, plus a RS Jr in Blackshear) to challenge for the ACC's top tier, and maybe even a good bet to make a deep NCAA Tournament run for the first time ever."

Together with Robinson and Clark, Blackshear and Hill are known quantities; it's Alexander-Walker who is in position to make a huge difference. If he can build on last year, Tech will be very dangerous.
