The 49ers hosted five free agents for workouts on Tuesday, four of whom are wide receivers.
All four of Cody Core, Chris Lacy, Shawn Poindexter and Damion Willis have something in common. That is, they are all young wide receivers over 6-foot-3. It's clear the 49ers are looking for a specific type of receiver.
Is there any particular reason as to why the 49ers are targeting tall receivers? On the active roster, Jauan Jennings (6-foot-3) and Mohamed Sanu (6-foot-2) are the two tallest receivers. Both of them have played a somewhat prominent role in the offense through two games. Their jobs seem safe for now.
It's more likely that the four receivers brought in for workouts are practice squad targets. Travis Benjamin (5-foot-10) and River Cracraft (6-foot-0) are on the smaller side, so maybe the 49ers are looking to add height to that group.

The other free agent -- and most intriguing of the five players -- is linebacker Tahir Whitehead. A nine-year NFL veteran, Whitehead totaled 100-plus combined tackles in four consecutive seasons from 2016-2019. Linebacker Dre Greenlaw was placed on Injured Reserve following the 49ers' 41-33 win over the Detroit Lions in Week 1.
Whitehead, a seasoned NFL veteran, could be an excellent depth piece at the linebacker position.
