Another IDP trade value

Would you trade Harvin (ppr) for Watt (6 pts/sack)?

Heavily depends on the scoring system and how DEs are weighted comparatively to WRs.

Ppr, 6 pts for td, yardage pts; 6 pts per sack, 1 pt per tackle, .5 for assist.

Very much a sack heavy league. If I were comfortable predicting Watt having a season similar to his 2012 season, I'd say do the trade for Watt. But I'm kind of worried about Watt's value under Romeo Crennel. He could be in for a down year. That said, I'd probably not do it out of caution (although Harvin has his own concerns as well).
