Though I really suspect Luck/Griffin will go 1/2, or 1/3. Maybe just paranoia, but it's logical for the Rams or Vikings to trade a few spots down. After that, I guess it depends on whether Tyler Wilson declares and whether or not we can move down. I know I'm not sold on Tannehill, but I think we need to come away with somebody in the first 2 rounds.
I really don't see the Rams trading down. The most logical teams who would want to trade up would be the Redskins, Dolphins, Vikings and Browns. The Browns would prefer to sit this one out so the most probable team would be the Skins at 6. St Louis has a lot invested in Bradford and they need to either protect him with an elite LT or support him with an Elite WR. If they trade down to 6 or below they will not get either. Kahlil is the best tackle in the draft and it isn't close. He will go either 2 or 3. There are other tackles (2 potentially) that could go in the top 10 but both are far inferior to Kahlil. If they trade down to the Skins and Griffin is off the board, we most likely will take Blackmon leaving St. Louis without the top WR or top Tackle in the draft. I don't see that as a win for them. The only way I see the Rams trading is if they fool us into thinking the trade with Washington is real and we have to move up to 2 in order to get Griffin. At least then they will be assured Blackmon at 4 and will be able to pick up another high pick.
Minnesota I see as the real threat to trade down. Most mock drafts have Minnesota taking Kahlil or Morris Claiborne depending on what St. Louis does at 2. If they were to trade down to 6 they would lose out on Kahlil but Claiborne will most likely be there and will be a better value as most CBs don't go as high as 3 in the draft. All Washington has to do is get 1 pick in front of us to take Griffin so I see that as a real possibility.
According to this draft pick value chart
http://www.draftcountdown.com/features/Value-Chart.php the Browns would have to move...
#4 and #22 to get #2
#4 and #36 to get #3 and #99
Washington would have to move...
#6 and most likely a #1 next year + something this year for #2
#6 and #38 to get #3
That's a lot to move up a spot or 2. I can see Washington being bold enough to commit to whatever is needed to move up. I guess I'm ok moving our 1st and 2nd rounder to move up 1 pick and grab a 4th rounder if Griffin is our long term answer at QB.
To move up to #1 and get Luck it will most certainly take the #6, #22, and the 1st next year to do it. Might take more but who knows.
Hopefully Tyler Wilson comes out because he will be there for Washington and they may be content with him instead of paying the high prices to move up. I don't want any part of Tannehill unless we don't get a QB in he 1st 2 rounds. However; Tannehill won't be there in the 3rd, he will probably see a Christian Ponder type rise and be a mid to high 1st round pick. Nick Foles in the 2nd or 3rd round would be good value. Still I would like to see us take Griffin instead of taking a project or FA pickup.
