I am no Browns fan, but I love draft talk. As a Bengals fan, I say take Leon the lion. We'll throw our #3 and 4 receivers out there and watch him get tourched (who the hell actually thinks this guy is the best CB in the draft?).
The problem the Browns face is their needs don't match the talent at the top. If Russell is there, I doubt Savage could pass on him (and in the LONG of it he'd be a good pick). Assume Russell is gone and now Johnson is the best talent on the board, WR not an area of need. That leaves Thomas or AP. With both obvious needs, deside if Thomas is really the dominate LT needed to protect Fry's blind side or the reincarnation of Robert Gallery? I'd hate to be the guy who wasted a big pick like that on the next Gallery. Now we have AP. Hands down the best back in the draft, but injury prone. The last thing the Browns need is another injury prone skill player.
Here is what the Browns really need to hope. Russell goes #1 and Quinn #2. Now, somebody is really drooling over Calvin and willing to move up. Now you land in the 8-12 range and land Lynch or possibly Adams. Either would be a good fit for you. With your extra pick in the second round, grab a solid fit for the OL.
