The Giants reportedly have some interest in possibly bringing him back as a center next season, but it appears as though they will have some competition for his services.
Boothe, 30, appeared in all 16 games for the Giants, which included six starts at center.
Pro Football Focus has him rated as the No. 46 guard in the league in 2013, which is due in large part to his underwhelming rating as a pass-blocker.
The Giants recently signed Walton and former Chiefs G Geoff Schwartz to bolster their interior offensive line.
