I think my team may be in trouble... WHIR

[mzkp54]

So after a few injuries, I'm a little concerned about my team. It's a 12 team PPR league. 8 teams make the playoffs, so I'm more worried about having a solid team come years end, because my chances of making the playoffs are pretty high.

Here's my team:

QB- Fitzpatrick
RB- McCoy, Hightower
WR- Andre Johnson, Mike Williams
TE- Gates?
W/R- Tolbert
W/T- Julio Jones
K- Hanson
DST- NYJ

Bench:
D Moore, Henderson, Ward, Cruz, Ridley, Roethlisberger, Chandler

With Gates and possibly Andre hurt, and Hightower losing carries rapidly, and Williams looking like he's heading into a sophomore slump, I'm pretty nervous about my team. I think my biggest holes are RB2 and TE while Gates is out. I just don't trust Hightower right now but don't have a better option.

I'd love to get some feedback, or ideas on how I could improve.
Thanks, and leave a link
