He will absolutely not be a solid 2/3. He is a fast guy who is not particularly game-speed fast and has zero suddenness. Aside from his awesome catch last night, his hands and contested catch ability are mediocre. His route running looks like it may have taken a step forward up to average. JAG. He is one in a long line of JAGs who have made plays and popped here or there over the years.
Edit: also, once the rest of the Chiefs receiving core is back, TT will go back to rarely seeing the field and rightfully so.
