Waiver wire question please help

Im dropping the Seahawks def for the chargers hopefully. im also dropping Anderson to stash Herndon the next couple weeks. I have walker as my TE and nobody else. Waiver is rough on TE right now with Graham being my best option. Should i stash Herndon or grab another WR like Marvin Jones?.. Even though I dropped him last week. Haha. My league is a 12 team .5ppr
