Sadly, this is not the first time I have seen this sentiment on this board. Takeo Spikes was a top 3 OLB before his injury, had an absolutely beautiful 2004 season AND in his only action THIS YEAR, he got a sack and forced a fumble that was returned for a TD.
IF he can return to his pre-injury form, then he is our best defensive player, and possibly best player overall. PERIOD. His salary is big because he deserves it.
