Guards should have massive bulk over 300 pounds.  He will create lanes for the interior running game.  He locks on a player, must overwhelm defenders.  He gets under a defensive lineman "pads" - that defender is finished.  He drives his legs and finishes his blocks.  He takes blocks to the second level.  For playing a guard position you must be fast to lock on middle linebacker.  During the games he must show the quickness to block a linebacker at the second level.

Guards will trap and folds.  The guards will slip behind center who has blocked down, and comes out on the middle linebacker attemping to drive him off the line of scrimmage.

Center... Most defenses use 4-3 Defense.  So for the most part, the center must hit, block what is called moving targets.  A moving targets is the middle linebacker.  Some defenses will make their defensive tackles play in what is called shade, between the guard and center.  The center must step up and block on angles.   Some defenses will make their tackle [4-3 defense]  play during the game right over the center, to create bull rush up the middle.  So the center must have the strength to take - over his head massive defensive tackles.

Hall of Famer Jackie Slater [Offensive tackle] knows what happens when offensive line punishes a defensive line.  Two Games in the playoffs show this: On January 6, 1980 @Tampa Bay [NFC Playoffs] Before the day was done, both Bucs defensive ends - Lee Roy Selmon and Wally Chambers had been sidelined by the pounding they took by this Rams offensive line. The other offensive tackle was Doug France.  He was also from Ohio State.  These two offensive tackles on the same offensive line: best the Rams had together.  The point is our current tackles or tackles we get I feel should be similar to these two tackles.  Trust me having tackles like France and Slater on the same line, you will send defensive ends to the sideline beaten up.  On passing downs both would take their defensive lineman straight up, no help.  What that means is no such a thing call double teaming with a tight end or running back.  It just didn't happen period.  On December 31, 1989 @Philadelphia [NFC Wild Card] Slater dominated Philadelphia's defensive end White from start to finish.  Slater in 1989 was named NFC offensive lineman of the year.

Notes... France in 1979 was NFL's best offensive tackle, by the NFL Players' Association. France was NFL All-Rookie 1975. Slater in the summer of 2001 was named in the Pro Football Hall of Fame. Slater was NFC Offensive Lineman of the Year: 1983, 1986 - 87 and 1989. Slater received in 1992 the Daniel F. Reeves Memorial Award and Ed Block Courage Award: both are Rams Honors Saul was a solid player. Hill received in 1979 the Carroll Rosenbloom Memorial Award (Rams Honors) Rookie Kent Hill started his first game on Oct. 14, 1979 in Dallas, Sunday night. He filled in for John Williams, at left guard.  Kent Hill never looked back.
