But tag him they did. And now he's "owed" 10% of the team's salary cap - so those other 52ish (not sure if they expanded the roster) players get the rest. Or they could sign him to a long-term deal, but he'll have to be well compensated, having been tagged.
And frankly neither they, I, nor you know if he's worthy of that kind of money. Maybe he will, but who knows?
So, we heard recently that the Dolphins may be $20 million or so under the cap. Take away this $12 and they only have another $8 to spend. Ya ain't getting any big-names with that, since the rules are spelled out about how the money can be used (whereas before you could play a shell game).
Given that, it seems to me this is just another in a long line of mis-steps with the furious enigma (Ireland).
