That really says it all. I was excited when the Titans got Markelle Martin late in the 2012 draft because he was really good at times at Oklahoma State, but as Wyatt said, he just couldn't ever get healthy here. It is a shame because he had the potential to be a guy that could have pushed for playing time here.
That tweet also mentions that Kevin Walter was officially moved to PUP (the rest of the moves can be seen here). That gets the Titans roster down to 75 players before today's deadline.
