Instead they need to work on Tannehill's deep ball so that Wallace can be used properly.
Wallace has a small catch radius...period...you will see the difference when Tannehill throws to Jordan and Stills.
Could Tannehill improve on deep throws?.....Could Wallace be better if he fought for the ball more...adjusted to the ball better...caught balls away from his body better....the answers are all yes....which is why Wallace is not an all-pro....and Tannehill is an improving but not yet elite QB.....and why they are not a great fit.
