We have significant upgrades at safety (but older and more expensive), guard (also older and more expensive) and FB. At WR we got younger and cheaper but maybe not better. At edge we lost two starters and got one older, more expensive player. We lost Tonga and replaced (presumably) by our younger, cheaper depth player. At blocking TE we got a younger, cheaper upgrade.
At this point our run game has gotten a significant upgrade. They have very athletic players on the left side and center, nicely suited for zone runs in conjunction with our new FB and blocking TE. Still have a right side suited for power runs.
