Your usage of the word "woof" is so fresh and hip it hasn't even made urban dictionary yet. Here are the top 3 urban dictionary definitions, none of which seem to apply.

woof
(1) basically the same as “oof” but cooler. woof i just spilt my venti iced coffee. that sucks woof i need more coffee.

(2) In the gay community, it's an adjective used to describe a sexy guy, but not the feminine kind of guy, but a more masculine guy; one who you wouldn't identify as being gay if you saw him on the street. If you see a hot guy, you say: "Woof!" He's woofy!

(3) verb: to declare something bad, ugly, terrible, or nasty. interjection: use as an expletive to express disgust or surprise.

Anyway, if you didn't mean definition 2 (haha), may I suggest an alternative subject line for this good news?

1. Wow.
2. Nice.
3. This is good.
4. Cool.

Or — and this might sound crazy but it could be the best yet —

5. Te’Jon Lucas, before transferring to BYU, turned down an offer from Kansas.
