I don't do online mock drafts but we just had one in my local community.
At 30 I traded down with Eagles for picks 32 + 134.
At 32 I traded down with Titans for picks 35 + 120.
It was only one round, so I technically did not pick, but Browns stayed at 33 and were ready to pick QB, and I was guaranteed to pick either Amos or Hairston at 35 (Grant went at 10 lol and it was the only crazy thing that happened).
So CB at 35 and then picks
56 + 62 in the second round
109 + 120 + 132 + 134 in the fourth round
With all these picks Beane could make any trade up in the second round or get into the third (or both).
I really hope he'll be able to pull of something similar.
