Yes, the Packers drafted a center in Corey Linsley of Ohio State in this year's draft. However, that was on the third day and it'd be a pretty big surprise to see him start from Week 1.
In fact, the Packers are already set to give J.C. Tretter the first stab at the starting job, according to Tom Silverstein of the Milwaukee-Wisconsin Journal Sentinel. The only potential problem with that is that Tretter is only entering his second year in the league and didn't play at all last year.
That's a lot of faith to put in the player who'll be snapping Aaron Rodgers the ball on every play. And what would the Packers do should Tretter not live up to expectations?
This is why they need to go out and sign a veteran center for their roster. That way if Tretter gets injured or struggles, the Packers would have a experienced starter to turn to instead of a fifth-round pick.
One name that sticks out is David Baas, a former member of the New York Giants. He's started 84 games over the course of his career and has been on a number of successful offensive lines.
By adding Baas, the Packers would have some insurance at one of the most important positions on the offense.
