These last few guys, especially the next three, can really go in just about any order. The seperation between these guys is minimal, but hey, thats what makes these meaningless rankings fun.
Since taking over in the middle as a strong-side ILB for Jonathan Vilma, Harris has emerged as one of the premier inside linebackers in the sport. He has excellent recognition skills and sniffs out screens and misdirections. He takes on guards and fullbacks with a ton of physicality, and rarely misses a tackle. He's not the greatest in coverage, but Harris is an absolute "thumper" in every sense of the word.
Harris is the yin to Bart Scott's yang; he is much more reserved, but once he puts on the pads, you wouldn't be able to tell which one is quiet and reserved. Voted team MVP by his teammates last year, Harris is one of the most valuable components of this team and should be around for a long time.
Hint for #4: If I gave you a hint, it would be way to easy. Instead, tell me what your top 4 players would be, and see if they match up with mine.
