Let's say Tucker improves and holds the fort till Adams returns, remembering that Tucker has had no experience at LT until being moved there late this year...Let's also assume Adams comes back strong, not a liability all next year.
Let's assume Larry Allen stays at his current level at least and that Rivera plays better next year having had a season to recover from his back problem and a new system and team.
Clearly, IN pass protection, RT is our biggest problem...Pettitti doesn't have the athletic ability or the technique yet...maybe he gets better in time, but only fools would count on him at RT next season...we desperately need to bring in a veteran RT in FA.
However, having watched him more closely in recent weeks, I have no doubt that the biggest problem with our running game is our Center. Johnson needs to be replaced...period. He is the worst run blocker on our OL...He cannot reach a DT without being driven into the running lane. From what I've seen, we actually block pretty well at the point of attack, but our RB either gets pulled down from behind by someone overpowering Johnson in the middle or our RB has no cutback lane because Johnson almost never seals anyone off without them getting into our backfield.
I know we're all concerned with the pass protection and our OTs...that's a given, but I'm convinced we won't significantly improve our running game until we bring in a better Center. Gurode can be that better center, but clearly he still doesn't have the brains or recognition to make the correct line calls. The fumble we gave up against Washington to start the 2nd half wasn't completely poor blocking by him, but as Parcells said, he made the wrong line call and then couldn't make the block.
I'd love to bring in a legit Center if possible, a veteran RT, and leave Gurode as an option at Guard.
