It just so happens that some GENIUS wrote a waiver wire article on Fantasy Football Cafe last night, and he really hit the nail on the head. Seriously, though, It discusses why Kaepernick, Myers, Hillman, Hilton, Edelman, and a couple others are smart pick-ups this week. Check it out! http://www.fantasyfootballcafe.com/tips.php
After you check out that GURU's article
here are some other thoughts for your situation:
If I was looking for a TE I'd pick up Myers if he's available. If not (can't believe I am going to say this) grab Pettigrew. The guy can barely catch a ball to save his life, but Stafford keeps throwing him the ball and I think he's the best TE out of the guys you have listed. Then it's Pitta right behind, followed closely by Dreesen, then Chandler, then Tamme, then Clark. Your league has quite a few decent TE's available, fortunately for you!
This might sounds crazy, but if I were you this would be my Week 12 lineup:
QB: Matt Ryan is easily a top 5 play against Tampa Bay. Start him.
RB1: Jalen Parmele - is getting his big shot as a bell cow, against TEN (drop Titus)
RB2: Ronnie Hillman - gets his chance vs. KC (drop SD defense - no need for them)
WR1: Brandon Marshall
WR2: Michael Crabtree
Flex: Darren McFadden (looks like he'll back)
TE: Pettigrew (if Myers isn't available)
DST: NE Patriots
