What do you think of these what if scenarios and priority changes?

QB- If Grossman signed-- move QB down to a P5 or P6-- not that we solved the problem but the likelihood goes down of us picking higher and especially if Griese is not moved.  

WR-- if we lose berrian-- keep the P2-- just cause JA is very unlikely to pick a WR in the first.  I would move the priority to M2 meaning we will pick twice in the higher rounds.  This would obviously change until a move is made in FA.

OLB- If Briggs is kept keep at P4 strictly as a value pick for depth.  If Briggs and ayanbadejo are gone still keep it at a P5 making sure we do get one pick in for depth as we do have starters still at the position.

OG- If Left Guard is bought-- then move the priority down to P5 strictly for depth here as well .  For now was going to move it up to a P2 as R. Brown is not coming back and they did talk to the top guard in the draft the other day.

Any input would be great as I decide to make these changes.

Here's detail on how the code works for the Drafttek.com site:

Team Needs
Code Descriptions
1 (or P1) - This is the absolutely highest priority team positional need.  If a player position (PP) is assigned a P1 code, the program will reach to fill the need.  For example if a team is selecting 15th, the program will search to the 25th player (as an example) to fill the P1 need.  A team can have only one P1 need.  However it is acceptable to have no P1 needs.
2 (or P2) -  PP's designated with P2 indicate that the that the team is in great need of starting calliber talent and will reach to fill the need.  The reach isn't quite as great as P1.  There can be multiple P2's identified per team.
Regarding Reach, the reach limit changes as the selection number increases.
3 (P3) - PP's (Player Positions) designated with P3 indicate that the team is in need of starting caliber talent, but will not reach for it.  Some teams use a "best available player" draft discipline, this fits the P3 code well.  
Two notes on P3:
a) even though we say "will not reach", there is a little bit of reach.  Selection #25 could reach to the #30 rated player to fill a P3 need.
b) If the program cycles through all the P1, P2, P3 and P4 needs without finding a player, the program will add more reach to the P3 PP's and seach again for a P3 player.
4 (P4) - PP's tagged with a P4 code are depth needs.  P4 is purely a value oriented selection, so there is no reach.
5 (P5) - The P5 code is used to identify positional needs that the team absolutely wants to fill (within reason), but does not want to invest a high draft pick.  P5 PP's start the simulation as an equivalent to P4 (depth needs), but in the 4th round all P5 PP's are promoted to P3.  Thus the chances of the PP's getting a player fill increase dramatically in the 4th round.
6(P6) - The P6 code is used to  identify late round fill needs - like a kicker, fullback, or backup QB.  
P6's have very low priority in rounds 1-5 and will only fill a player under the most unlucky of circumstances for the team.
In the 5th round, a conversion takes place and all P6 PP's convert to P4.
P7 and P8 do not exist.  They did once but were replicative and never seemed to fill.
9 (P9) - PP's tagged with a P9 code will not be filled under any circumstances.  The program simply bypasses them

M Codes Descriptions
Originally  the "M" degnation stood for "Multiple" indicating that a team was looking to find more than one player at a given Player Position (PP).  
Most player positions do not have the M designation, in these cases, if a PP is filled, the PP will be reset ro P9 so that there will be no further players selected at that position.
But if the PP has an M code next to it, the reset will be based upon the M code.
M2  - PP's (Player Positions) appended with M2  are for teams with multiple starter level needs at a certain position.  
Assume that the WR position is coded as a "1" with an M2 next to it.    After the first WR is selected, probably in the 1st, maybe 2nd round, the priority code is reset to P2 (internally) and the M code is reset to a blank.  Likely  a second WR will be selected within the next couple selections given the P2 designation.  Then after the second WR selection, the priority code will be setto P9 so that no more WRs are picked.
M3 - PP's appended with an M3 code will get the PP code reset to P3 following the first selection at the PP.  This also indicates a desire to add a second helping early on.
M4  - PPs appended with M4 will have the PP codes converted to P4 following the initial selection at the PP.  This implies that the team has a starter level need, then a 2nd depth need at some position.
M5  - PPs appended with M5 will have the PP codes converted to P5 following the initial selection at the PP.  This implies that the team has a starter level need, then a 2nd depth need to be filled in the mid-rounds.
M6  - PPs appended with M6 will have the PP codes converted to P6 following the initial selection at the PP.
