They've definitely stockpiled picks, just in case Cody Kessler isn't the future face of the franchise.

Well, yeah. So, I thought it was in this thread, but... whatever. In the end (for 2016 plus the future ones) they essentially transformed the #2 (Wentz) pick into 8 draft picks (and if they trade down any of the future ones, next year's 1st or 2018's 2nd, it will be more). So, it will be a while to see if that was worth (especially with a 1st and a second still outstanding)
Now, having said that, I think we've seen what the "analytics" department is causing to start with.
1. They have some model that tells them that the more picks you have, the more likely you are to hit on guys. And they probably had some threshold that says, if you take any 14, they'll probably result in X pro bowlers, Y starters, Z back ups and some number of guys that don't make it. Further, because you have to be able to compare quality and quantity, they probably have some other metric that tells you based on the number above that it takes X third rounders to get the same result as one 1st Rounder as far as likelihood of success. (Probably to the degree that they expect only 2 hits out of the 4 Receivers not named Coleman, but, they really wanted to go for 2, and if they get lucky, the TE will work out, personally though, I think they were caught off guard by Higgins still being on the board and they might have decided he really was the BPA there.
2. This approach will, I think lead to a priority on productive college players since to analyze, you need data sets, and well guys that have observably done stuff are going to show up more than those that haven't. Then they factor in measureables (Both plus and limiting) and then the scouts opinions. (Minus bong hits through a gas mask, etc)
So, I mean, obviously the priority here was to improve at Receiver and affect the QB on D.
Generally though, most of the people who didn't like the Browns Draft didn't like the Kessler pick, and thought Ricardo Louis went too high. (Most of them did like Shobert - Who I'm not convinced they don't see as an ILB and Higgins). Not surprisingly the Analytics outlets loved it (PFF for example) and the I know football players when I see them types don't.
But at the end of the day, you get 7 picks alotted to you, and mostly those guys don't all end up contributing (even on teams not called the Browns) and I think they're goal here is to try to hit more than 50% of the time, so, if they do well with 8 or 9 of them, that's more than if you hit on all 7 of the original ones (I realize I haven't accounted for compensatories here, but, the long term view is what's important)
The downside for all this to me is, can you develop/evaluate all these guys, especially the WR's between now and September since you can't possibly keep them all, so then is it worth all the trade downs for guys you'll eventually release. On the other hand you can trade picks for guys and end up with the 2008 Browns Draft... with the exception of the blind squirrel finds a nut grab of Ahtyba Rubin... you got zip and zilch out of it.
