The problem with this roster is an overall lack of talent at certain positions, primarily the secondary, and DT. Poor pass defense is what has prevented this team from winning championships over the past several years. All those BB draft misses with high round draft picks is the main culprit. Again:
1.) 2007: FS Brandon Meriweather, 24th pick overall;
2.) 2008: CB Terrence Wheatley, 62nd overall, and Jonathan Wilhite, 129th overall;
3.) 2009: SS Patrick Chung, 34th overall, CB Darius Butler, 41st overall;
4.) 2011: CB Ras-I Dowling, 33rd overall pick;
5.) 2012: DB Tavon Wilson, 48th overall pick.
Six of the above seven named DBs were high draft choices taken no later than the second round. As a direct result of these busts, BB has had to find players through free agency or in the later rounds to fill out the backline of his defense. BB's big free agency addition was 33 year old has been Adrian Wilson.
At DT, BB has not addressed the position since 2004. Other than bust Ron Brace, selected 40th overall in 2009, and DT Kareem Brown, selected with the 127th overall pick in 2007, I can't remember when BB has used a 4th round pick or better on this position. He's had to spend so many high draft resources in hopes of building up his weak secondary, that this position has suffered. Now, pro-bowl D Vince Wilfolk is 32 years old, and the remaining of the Pats' DTs were obtained off the free agency scrap heap. Poor-average DT play means no interior pass rush...which is the best way to disrupt a passing attack.
I hate to keep saying this, but BB's poor drafting has cost the Pats dearly.
