For the record, I was against the extension because I feel contracts should not be too malleable, that's why you write them in the first place.
First, I was surprised and disappointed by the FO writing a new contract for "X". Second, I was astonished and delighted by the structure of the new contract and feel this will be the kind of contract (in terms of requirements) that we will be writing for every player after their rookie contract ends.
"X's" skill set was never a concern for me during all this time.
I see his future with the Dolphins as doubtful after this year because his new contract calls for a contract review at the end of the season.
1) If "X" plays well, the cost to keep him will most certainly go beyond what we will be willing to pay him while some desperate team will pay him an extrordinant amount.
2) If "X's" performance slips, we will want to pay him less and there will certainly be teams willing to pay him more.
In either case, I see "X" going where the money is.
