Jovorskie started off well last year and was springing holes left and right for Reggie and Lamar Miller. As the year went on, he wore down, thus becoming less effective. I guess that's to be somewhat expected when you take a year or 2 off of football and then goto the NFL.
While personally i love Jovorskie, i think Charles Clay would be a good look and make the offense wholly more versatile. I don't think he has Jovorskie's running blocking instincts, but what he lacks there he makes up for in pass catching ability.
