49ers LB Elijah Sullivan

Like their wide receiver room, the Niners also have depth about their linebackers where the intent is to find players who can compete with the No. 3 option on the roster, Azeez Al-Shaair.

One of those brought aboard was Elijah Sullivan, who spent six years at Kansas State and dealt with some injury setbacks that likely affected his draft stock.

At 6-foot-0 and 215 pounds, Sullivan looks more the part of a free safety instead of a stack linebacker, although he could be put into a position where he could play in a weak-side (WILL) role and on special teams.

He does have the speed. But unfortunately, the size just isn’t there. What seemed to be the case all too often is Sullivan getting bumped off by bigger receivers while getting absorbed by even smaller-sized blockers.

It’ll be tough for him to overcome those challenges during training camp.

Sullivan did receive $125,000 in guaranteed money for his rookie contract, and that’s substantial.

Still, he’ll have to outperform a number of other linebackers to stand a remote chance of hanging around, which doesn’t seem likely.

Prediction: 49ers waive Elijah Sullivan before Week 1
