2015 NFL Mock Draft: Marcus Mariota to Tampa Bay

<p>The 49ers could look to add depth by selecting Collins who could play tackle or guard at the next level. Mike Iupati is scheduled to become a free agent and it does not look like the 49ers will franchise tag him. He has a big frame at six-foot-four and possesses a strong frame. Collins has solid upper body strength and good hands and that allows him to become a dominant blocker. If Iupati leaves in free agency, they could look to select his replacement with this pick in the big tackle from LSU.</p>. OT. LSU. La' El Collins. 15. player. 42
