I can offer a Jets outlook....
As of now, it loks like the line will have the same starters, but I do expect at least one first day draft pick to upgrade at RG or RT.
LT- D'Brick Ferguson- He was what I expected, a rookie LT that had a rep for being less than a stellar run blocker, and a guy who will have trouble against a bull rush in pass protection. Check and check. His rep for struggling to keep weight on was also apparent and he wore down late in the season giving up 10 sacks, mostly against bull rushers. Can he beef up, get stronger and keep the weight on? He can pull and block in space, as can his rookie counter part Mangold, but those atributes were not utilized very often last year.
LG- Kendall- A solid vet, but getting old.
C- Nick Mangold- Best player on the unit. Smart, strong, should improve his second year. Only weak spot is against monster NT's. He is already the glue that holds the line together as the blocking assignment play caller.
RG- Moore- He's there because he's cheap. He's cheap because he isn't very good. The most likely of the five to be replaced on day one of the draft. Can you say Ramirez?
RT- A Clement- Was allowed to walk in FA... and in a year where FA O linemen were buying mansions and yachts, Clement had no takers.... and re-signed with the Jets. He's a below average RT, better at run blocking than pass blocking, but that isn't saying much. Hold the fort guy. He's the Alamo of that genre. He'll hold up, but in the end, he'll lose the fort.
So, the run blocking hasn't improved, beyond whatever development Ferguson and Mangold can bring to the table. Jones is NOT going to fix the Jets run offense. Slightly better, maybe, but I wouldn't put much money on that either, without some new blood on the right side. It was a rarity to ever see Houston, Washington or Barlow ever get through the LoS without getting hit. That hasn't changed, and few RB's can run effectively through trash like that. The pass blocking is adequate for the Schotty lite offensive scheme. Lots of quick sideline outs. More of the same, barring a solid rookie who could be ready to start from this year's draft.
