9, by my count. That would be players with more than 4 years in the league and who were not brought in by Garrett: Romo, Witten, Dez, Free, Scandrick, Church, Spencer, LoDouceur, and Parnell.
The number of those players who we presently start who were developed as starters under Wade shortens that list to Romo, Witten and Free. The other 19 starters were developed/found since Wade left. In our drive to the playoffs Parnell who was as green as grass when he came here was in the starting lineup and the offense didn't miss a beat. OScan basically was internally promoted from #3 CB to #1 CB.
So in our drive to the playoffs here are all the new starters who weren't starting when Wade departed:
Dez (you could argue this was inevitable but there were major growing pains)
TWill
Hanna/Clutts/Beasley (depends on the package we are using)
Parnell
Martin
Fred
Leary
Tyron
Murray
Selvie
Hayden
Crawford
Mincey/DLaw
RoMac
Hitchens
Carter
Moore
Carr
Church (he was a ST player under Wade who no one expected to become a starter)
JJ Wilcox
So that is 22 major players that were not starting under Wade. Now how did we acquire these 22 players;
1st round 4 (Dez, Tyron, Fred, Martin)
2nd round 2 (Carter, DLaw)
3rd round 4 (Crawford, TWill, JJ, Murray)
4th round 1 (Hitchens)
6th round 1 (Hanna)
Prem FA 1 (Carr)
Scraps 4 (Mincey, Moore, Hayden, Selvie)
UDFA 5 (Parnell, Church, Clutts, Leary, Beasley)
Trade 1 (RoMac)
So we seem to have a December roster whose major cogs were largely developed after Wade left. The only real indentured starters who are basically in the same place serving the similar roles are Romo, OScan and Witten. You could certainly put an asterisk besides Dez but since Wade left there having been times of major growing pains when many wanted to throw him under the bus. Everyone has to remember Dez was not a top 5 game he came here and dominated from game 1. It was actually about halfway into his 3rd season where things started to click for him.
Furthermore only 7 of those cogs were brought in with premium resources (1st/2nd round picks, high priced FA).
It has been an outstanding job from this whole organization to build this team including college scouts, pro scouts and the coaches to form this ragtag group into a collective unit of *** kickers.
Now the ongoing challenge will be to continue to find and develop cheap cogs so the team can continue to have the depth needed to win in December. We have absorbed missed playing time to projected starters like Sean Lee, Free, RoMac, Durant, Melton and Mo and have just continued to churn out wins.
