No. 3: 49ers ‘Defensive’ Tackle Trent Williams
Of all the imagined San Francisco position switches out there, the one that would require the most fine-tuning and adjustment would be taking left tackle Trent Williams and placing him on the other side of the line of scrimmage.
Never mind the hole it would leave in Williams’ spot on the offensive line. Or, heck, he could merely play both roles anyway after doubling as a defensive tackle. Remember, footballers used to do this all the time during the 1950s and early 1960s anyway. And Williams’ perennial Pro Bowl pedigree suggests it could be possible.
Williams might not have the quick twitch necessary to be an outside pass-rusher. But as a 3-technique interior defensive tackle, it’s not hard to envision his sizable 6-foot-5 frame standing as an imposing figure for any interior blocker.
True, Williams might have to shed a little weight to get down from his 320-pound frame. Yet his already Hall of Fame-level of understanding how blockers succeed could easily help him translate his game over to the defensive side.
Plus, with most interior defenders reaching the highest levels of success if they’re both strong and fast, Williams should easily be able to check off that box:
Now just put that idea into a bull-rush move and imagine how a pocket would look like if Williams was delivering that kind of punch from the defensive side of the ball.
