re: Three specific things I think are hurting this team.

We need a good defensive coordinator that can do something for more than 1 year.

Take a look at who we have on the teams from the draft picks/UDFA:
2007: Meachem, PT (UDFA)
2008: no one
2009: Morstead
2010: PRob, JG, Bush (UDFA), Galette (UDFA)
2011: Jordan, Ingram
2012: Hicks, Toon, White, Jones
2013: Vaccaro, Armstead, Jenkins, Stills, Hill, Lelito, Khiry Robinson

Our picks the last few years have been good, but the players are young as hell and their ceiling isn't as high as you'd hope for. White is never going to be a shut down corner, Toon is never going to be a #1 receiver at this rate, Hicks is becoming a disappointment, and who knows what Jenkins is. Stills is hampered by his quad still I bet as well.

We got issues and the lack of OL/DL play is gonna get us killed.
