What are your 2 biggest concerns on each side of the ball going into this season?  

For me they are:

Defense:

1. With Denzel Burke gone Igbinosun is going to have to run with the oppositions #1 receiver.  Can he step-up and handle that assignment and not fall back on his handsy, penalty drawing habits?  I've heard he's looked good in camp but I never know if I can trust camp reports.

2.  New DC.  Will Matt Patricia over-complicate things in a way that college players can't handle. I haven't heard anything about this being a problem in camp but it seems like he is really having guys line-up at a lot of different positions in order to have a lot of flexibility.  Hopefully it's not a problem but I worry that we may end up with guys missing assignments due to some confusion.

Offense:

1.  Performance of our 2 new OT's.  I think we will be fine but there has been a lot of talk about our DE's/edge rushers excelling which could imply some pass protection problems at the OT positions. I know they moved Austin to left tackle to address this so hopefully it's ok.

2. Play calling. New play caller's always are a concern. I know Day will step-in to assist when needed but this is the only other area on the offense that concerns me at all.  

We clearly have a lot of high end talent on this team so it comes down to how quickly the coordinators can get them up to speed and game ready.  I could see anything from a 0 loss regular season to a 3 loss regular season so I expect a good season.  How good remains to be seen.
