Great, you have the 6.3m or whatever to go signa Tackle. Look at Ring 6's list, sort by position. The ONLY tackle there rated higher than Chuks was Nijman, and barely. You can't just say, "they should have signed a LT!" without offering a choice.
Look, I hate this as much as the next guy, but that $30 million CAP boost nailed down the top players to their teams, particularly those at premium positions, like T and WR.
I'll give the FO another year, thanks. They've got a ton of cash, will have another high draft pick (and not needing a QB), and hopefully - hopefully - will know what they have and what they need because the kids are playing. They certainly need blue chip talent and there should be some on the market.
