Lions to hone in on center in draft?

The Detroit Lions re-signed center Dominic Raiola last month, ensuring that the longtime Lion starter plays his thirteenth year in the Motor City. Raiola and the entire offensive line had above average years last season and he likely has a year or two of high-level play left in the tank. Still, Raiola is 36 and his contract is for one year. Thus, it appears the Lions will be at least taking a look at replacements around draft time.
