The one thing I noticed yesterday is how much more fluid his throwing motion has become since the 1st game against the jest.
His accuracy isn't Sanchez/Tebow terrible but could be improved. This IMO is where Keenan Allen and/or Eifert could greatly help the phins O & RT's progression.
They could line Tannehill up in the pistol to take advantage of his athleticism. However, its a recipe for disaster w/ mediocre line play and no 'electricity' on offense.
