Agreed on most points. Where I disagree: Watson is not agile. He seems to excel in his straight-line speed and his great strength allows him to break tackles. But last year his strength did not translate into consistent blocking.
Thomas blocked pretty well for a rookie, showing good technique, and in his one (and only one) breakout game, showed good hands, good route running, and agility and balance when running after the catch. Watson needs more open field to accelerate. Once he does, he can outrun anyone. Last year, Watson saw tight coverage and never had any open field. So before anointing Thomas the #1 TE, let's see what happens with Watson under these new circumstances.
A lot of people are dinging Watson because he struggled as the focal point of the offense, dropping a few catches, some after particularly hard hits, and fumbling. This year, he's been reliable in his limited opportunities.
As for intelligence, Watson has struggled in the past to react properly to defensive coverages. This has nothing to do with wonderlic scores. This is field vision. Football smarts. So far, we haven't seen Thomas out of position for a catch, again, in limited opportunities.
Thomas has greater potential mostly because he's done so little, but also because he's made the most of his chances. Watson had a huge opportunity to stand out and did not, despite his undeniable gifts.
For these reasons, I'm excited to see what Thomas can do. If he takes advantage of his opportunities as he did in the past, he will challenge Watson in catches per game by the end of the year.
