Sure. Anyone can debate it. And they'll lose that debate.

Larry Allen was listed at 330 pounds. He was probably really more like 350 pounds. He bench pressed 700 pounds for shits and giggles and ripped off like 50 reps of 225 pounds just for fun at one of those stupid pro bowl skills challenge things. Who can forget him hitting the jets and chasing down and tackling that defender who intercepted Aikman and preventing a pick 6 in the process. Larry Allen was freakishly big, freakishly strong, and freakishly light on his feet for a man his size. No one in any era could deal with him. IF he played in the eras before his time he'd have just dominated even more than he already did. Larry Allen literally scared defensive linemen, linebackers, and safeties and made them physically quit. They would just quit because they were so terrified of the punishment he was dishing out on them. There are clips of this guy launching 250 pound NFL linebackers 15 yards and tossing them around like they were rag dolls.
Anyone can debate anything. There is plenty of room for stupid debates. Debating that Larry Allen isn't the greatest guard to ever play the game is just a stupid debate.

Lol. Here’s the thing. I’d probably agree with you that he’s the best Guard ever but it doesn’t make it a fact.  Listing all his physical attributes doesn’t make it a fact.  I could list a ton of backs bigger, stronger, and faster than Sanders and Smith.
Larry Allen being bigger and stronger than guys like Bruce Matthews, John Hannah, Gene Upshaw, and Randall McDaniel doesn’t necessarily mean he performed his job better than they did.  Allen was great but he was human too. I have a vivid memory of a Thanksgiving Day game where Reggie White took one arm and clubbed Allen on his ass on his way to the QB.  That isn’t going to make Allen’s highlight reel but those plays occasionally happened to him just like everyone else.
