3. Giants OG Marcus McKethan
Marcus McKethan replaced Mark Glowinski as the Giants right guard before the Arizona game. Despite playing strongly in his debut, the second-year North Carolina player has struggled immensely. Last season, McKethan tore his ACL in training camp and missed the entire season, so this is his first year making plays.
McKethan barely played this preseason and has been thrown into the fire. PFF gave McKethan a dreadful 35.6 offensive grade for his efforts Sunday, the third worst on the Giants. McKethan's pass-blocking grade for the season is abominable and second worst among Giants line members, only ahead of Shane Lemieux, who is somehow still on New York's roster. McKethan's missed block during the Seattle game completely changed the game.
Glowinski is not a great option for New York at guard, but he is a better player than McKethan. It should be noted that McKethan suffered a knee injury against Miami Sunday, and the extent is unknown.
Justin Pugh was just added to New York's practice squad, and when he's ready, he should become Big Blue's starting guard alongside Bredeson. Pugh, on the right side of the line, would provide a much-needed veteran partner for Neal if Neal is still the Giants right tackle.
