Just to have a little fun with you before bed I decided to do a little research.
I looked up the current top tacklers in the NFL here (
http://www.nfl.com/stats/categorystats?tabSeq=0&statisticCategory=TACKLES&conference=null&season=2011&seasonType=REG).
I decided to look at the top 40, simply because #40 is where the very first New York Giant appears on the list (a FS, Rolle- our first LB would be Kiwanuka, at #57...).
I looked for LB's in the top 40 tacklers in the NFL who had also been drafted in the past 5 years, in the top three rounds, AFTER the Giants first pick in each respective drafts. Here's what I came up with (#'s in front of player are their position in the top 40):
1. Pat Angerer - 112 tackles - Drafted 63rd overall in 2010 draft
4. Navorro Bowman - 103 tackles - Drafted 91st in 2010 draft
5. D'Quell Jackson - 100 tackles - Drafted 34th overall in 2006 draft
5. Curtis Lofton - 100 tackles - Drafted 37th overall in 2008 draft
7. James Anderson - 97 tackles - Drafted 88th overall in 2006 draft
12. James Laurinitis - 90 tackles - Drafted 35th overall in 2009 draft
13. Sean Witherspoon - 89 tackles - Drafted 19th overall in 2010 draft
16. Paul Posluszny - 84 tackles - Drafted 34th overall in 2007 draft
18. Deandre Levy - 81 tackles - Drafted 76th overall in 2009 draft
32. Sean Lee - 71 tackles - Drafted 55th overall in 2010 draft
35. Donald Butler - 70 tackles - Drafted 79th overall in 2010 draft
40. Phillip Wheeler - 68 tackles - Drafted 93rd overall in 2008 draft
So there you go. And you know what's weird about looking at tackle stats? They're completely dominated by linebackers. Amazing, isn't it? Almost makes one think the position is important.
And those names don't even include the top-40 LB's taken in rounds 4+ or undrafted. (Kavell Connor, Jamar Cheney, Desmond Bishop, Wesley Woodyard, David Hawthorne). Nor does it include the guys the Giants had no shot at drafting in the 1st round (Chad Greenway, Patrick Willis, Brian Cushing). It sure seems like there are a quite a few LB's out there in the past 5 years that are making a whole lot more contribution than any LB's our Giants have had flailing around over the same time span.
And to be clear todge- you appear to be right: Good linebackers don't "grow on trees". Apparently, they grow in the first three rounds of the NFL draft.
