Well, yes, but his primary of expertise is on hadrosaurids, and growth, and
ontogenetic behaviors, and the like.  Not to say that he hasn't made
important insights in other aspects of paleontology (he certainly has), but
he isn't a tyrannosaur specialist.

See my article in the forthcoming DinoFest volume for rebuttals of these points.

(Incidentally, tyrannosaur eyes are IMMENSE.  They only look small because
the rest of the skull grows faster than the eyes do, an aspect of allometry
long known for modern animals and well established for dinosaurs through the
work of Jack Horner).
