Enormous praise from Bills legend Cornelius Bennett -- the former Buffalo star tells TMZ Sports he believes Lamar Jackson is "the closest thing that I've seen" to Barry Sanders.
Yeah ... heads up, Bills defense!!!
Bennett delivered the massive compliment to Baltimore's QB this week ... just before Buffalo will have to try to stop him in its playoff matchup with the Ravens on Saturday.
But, good news for the Bills ... Bennett says he believes Buffalo CAN slow down Lamar -- if they just use the same tactics he used against Barry in his career.
