Hell ya he's a viable starter. Watch him put it into the end zone. He may run, he may pass, but he gets the 6 points. Can Decker get him out of jams is the question for the future but for week 7? It's MIAMI for cryin' out loud. This guy's gonna get all the goalline action.
@ 2TD (1 pass 1 run) he gets 10 points. Then his 231 passing yards give another 11 points since 25 yds = 1 pt and at each 100 yards you get an additional point (not mentioned above but assuming) giving you 21 pts. Not bad. If he throws an interception that is -2, yu still get 19. Romo and Newton got 19 and 15 respectively last week. And it's his homecoming and all. Definitely viable.
Current Yahoo prediction week 7 in my league: Ryan-16.66 Tebow 13.56
*disclaimer: The 1st paragraph of this is what I heard on NFL Network's Fantasy show tonight.
They also mentioned his 17 fantasy points week 5, and last year 3 out of 4 fantasy games over 20 points. So he's like "four of five" (80% having a good fantasy week) for his career. Oh and that one game? He only played half. Let's say I revise the passing total to 189 yards passing. He still gets 18 fantasy pts.
