As expected, there are several areas of strength and some weaker areas. At first glance, I think depth is the glaring area of concern. Especially at OL, DL, and LB. Heck, even ST's has me slightly concerned (does anyone know anything about this Long Snapper. Miss james dearth).
I expect that Tanny will look to add depth to the roster with a few veterans along OL and DL once teams begin making cuts. In year's passed they have had Hunter/Turner to fill in for a game or two if anyone missed a game. They seem to be really depending upon Vlad in that area this season.
