I'm going to make a statement about game three of preseason, specifically the first quarter and a half when Mac and the starters were out there, and keeping in mind these are the Pat's starters versus mostly backups on the Raiders.
Outside of three "zone blocking" rushing attempts... which is the only thing people seem to remember about "blocking" in reading comments after this game, the blocking in this game was otherwise superb. Not just the offensive linemen... but the TE's, RB's and WR's as well.
In rushing, the "must have" plays on short downs where the O-Line fired out ahead or gap blocked it, they got the tough yards they needed. They created some big plays as well.
In passing, on the very first drive they were behind the count because of a "zone blocked" run for negative -4 yards previously. Mac dropped back to pass and had the cleanest pocket you could hope for, for some ungodly reason he ran outside anyway instead of just stepping up and passing. Opening drive nerves perhaps, they've been working on a lot of rollout passes the entire camp... but the pocket was clean. Any pressure he faced after that was because the clock ran out and nobody was open... he had forever to throw. Five seconds is a long time in the NFL.
Take away three zone blocks that all went for net zero or negative yards, and the blocking was great. They weren't scheming up a lot of offensive plays, they weren't scheming guys open, so there simply weren't enough guys open or the timing was off between QB and receiver.
They need to scrap the outside zone garbage or dial it back to where they use it in spurts like in the past... the zone run looks like sht.
If watching that quarter and a half tells you everything in 2022 is doomed, then you should probably go back to watching Antiques Roadshow instead.
One failed attempt at a scheme tweak in preseason doesn't make a season.
