We all know Landry is not great in coverage so that isn't a surprise. The biggest question mark with him is if he can stay healthy. This past year was a step in the right direction but I would like to see him do it again. Also, you need a true FS to play alongside him, one that is good in coverage. He does miss a lot of tackles b.c he plays @ top-speed all the time.
The criticism of Keller is spot on. Average at-best TE. Disappears in big games and is the only TE that Ray Lewis can cover.
