The thought process was to get their young QB some help as he had absolutely nothing at WR.
In the end it looks like Grier chose the worst option of the 4 available to him.
1. Stay at #3 and take Chase or Sewell.
2. After the awesome trade down to #12, stay there and select best player available, Parsons or Slater.
3. After wasting picks to move up to #6 at least take Sewell.
4. He takes Waddle at #6
I don't blame him for going after a WR at all, we had absolutely nothing and Tua desperately needed the help. I'm guessing he didn't go OL as he had took Ajax the season before (who was looking like a bust until McDaniel hid his pass protection deficiencies) but really Chase or Sewell should have been the pick if staying at #3.
Waddle was a good pick in the grand scheme of things but hindsight has shown there were better options available and Grier ended up taking the guy who is good, not great like he does a lot of the time.
A personal pet peeve of mine are the people who try to judge a GM by the production of his selections.
(1) Many selections are the result of other factors (Owner, HC, Scouting Dept, etc.).
(2) Many selections are made because the priority target just got drafted 1-2 spots ahead.
(3) Many selections end up booming/busting as a result of coaching, scheme, etc.
(4) A GMs job is really to manage so it's the logic behind the decision in the moment that matters, not the production years later.
One of the reasons I don't necessarily credit the Dolphins with Waddle as a "hit" is exactly what you say...basically any of the alternatives would've been equally as appealing.
The options were essentially Sewell (who was projected to be be very good) alongside the 4 receiving options: Pitts, Chase, Smith and Waddle. Every single one of those names has been a productive player. In that sense, failure wasn't in the cards at all, but as you say, there were certainly alternatives.
One thing I'll say is that having drafted
two OL the year before, the Dolphins really weren't going OL again using their highest pick. Both of the guys they drafted (Ajax & Rob Hunt) were drafted highly and went on to be good players so spending another pick on OL the very next year within the Top-10 just wasn't in the cards.
That also means you weren't staying at 12 and taking Slater. That too just wouldn't have been in the cards.
The idea of selecting Parsons at 12 may have been an option but the downside of that is that you would've probably selected a WR at 18 and that would've assuredly been a bust. Everyone forgets that after Pitts, Chase, Waddle and Smith were off the board the next available options were Kadarius Toney, Rashod Bateman and Elijah Moore...none of whom were very good.
So, as much as we may be frustrated by the OL performance in recent years, you just can't spend picks on the OL over and over without neglecting other areas and truth is, this was a great chance to get a premier receiver for Tua....we just missed.
Waddle is good but he is no Ja'Marr Chase, a player who's probably destined for the HOF.
This is kind of another example of how the Dolphins drafting is perennially mid....we do a good job of avoiding the unproductive busts but it seems to come at the cost of always missing on the
great players and it's just really hard to be a special team without those kinds of guys.
