Bears defensive end Israel Idonije is perfect, when it comes to finishing a tackle.
According to the website Pro Football Focus, Idonije is the only defender with at least 75 tackles over the last three years to not miss even one.
PFF analyzed all defenders with at least 75 attempted tackles, including sacks, over the past three seasons.
On the opposite spectrum, among defensive linemen, Amobi Okoye of the Houston Texans missed one of every eight attempts.
Bears safety Danieal Manning finished second among defensive backs, missing just 27 or one in every 27.57 attempts. And, not surprisingly, cornerback Charles Tillman was eighth among DBs with a miss, on average, every 18.5 tackle attempts.
Only one Bears defender made the dubious list. Lance Briggs had the most missed tackles (48) among linebackers, but his average (7.63) ranked fourth based on his number of tackle attempts. Among all the linebackers who made either list, Briggs finished tied for second with 277 solo tackles.

The fact Danieal Manning was ranked 2nd in fewest missed tackles is extremely impressive for the simple fact DB's are on an island for most of their tackle attempts. Kudos to Charles Tillman also, Tillman will go down as one of the better tackling corners before its all said and done, he's been doing it for almost a decade.
Whats most impressive is the fact the Bears, as a team, had so many players on this list, Idonije, Manning, and Tillman. And Lance Briggs had the 2nd most solo tackles, so, as a unit, the Bears are very reliable when it comes to bringing a ball carrier down. GO BEARS!!
