So according to your decision calculus you have to spend the first round pick where you wont force an existing or developing player out so lets look at the other positions.
QB: Romo starts a first on a QB is completely out of the question as it might push Romo out.
RB: Jones and Barber, again the same thing.
FB: Well Hoyte certainly performed better than Watkins at their relative positions so this is out.
OT: Adams, Columbo, McQuistan, well we wouldnt want to hider Pats development much less Columbos so this is out of the question.
OG: Kosier and Proctor: Well I guess you could justify the pick on a guard as Proctor is inferior but if we sign one of Steinbach Dielman or Dockery then this position goes by the wayside.
C: Gurode, well nope cant do that either.
WR: well this is our deepest position and with the ytoung guys in the wings we dont want to hinder their progression.
DE: Canty, Hatcher, Spears: noep for all the same reasons. Dont want to hinder them.
DT: Fergy, I guess since he is old the Watkins fan club will allow this.
OLB: Ware and Carp no way we can allow them to be displaced as ive been told its not a good investment
ILB: Ayodele and James; Ayodele is a good player so hes got to be protected and James played about as well as Watkins did so no there.
CB: Newman and Henry, well i guess the WFC will allow Henry to be displaced because hes not a rookie.
S: Williams and Watkins; nope becauese Roy is a probowler and Watkins needs to be allowed to develop.
K: the Watkins Fan Club will allow this because itd be a investment that would only push Martin if he is resigned.
So as it stands right now we can only use our first on a OG, CB, DT or K all other positions need to be coddled or will be a bad investment.
