my 2 cents
IF the OL comes together reasonably well and stays healthy
& IF the running game comes together
then…I think the reasons for predicting Foles will do well are that
* he can do a very good short to medium ball control, quick throw passing game—although that, I think, won’t be the whole offense, I have a hunch it will be a big part of it (if they continue in the 2012-14 tradition, ball control + power running will set up all kinds of designed big plays, including play action passes but not just that)
* he showed signs in the 2014 season that when the Eagles were not offensively dominant front-runners like they were in 2013, he could be clutch in comeback situations
Now for the question marks. His longball accuracy fell off in 2014, so I want to see him get some of that back. He wasn’t very good under pressure in 2014, but if the right things fall into place, he can maybe rein that in. He dropped off in the redzone in 2014, so I want to see him get some of that back too.
I am not very rah rah just yet because we haven’t seen him in action in this offense, but for me, the 2 things I list above are enough to start with.
What if the OL struggles? I think he will be hampered, but I won’t hold that against HIM. I would just wait until the OL was fixed or stabilized (for example if injured starters came back or young players improved).
