Concerning Hilton.....he is in no way a Gates or Gonzo, and I wasn't saying he would be. But if I had to pick between Davis and Hilton, Id probably go with Hilton. Hilton will be drafted many rounds later than Davis....IMO he is a sleeper and presents a nice value pick, not a stud. Gates is a stud and I have no worries (baring injury) that he will finish top 3-5 (at least) TE regardless of QB.
As far as QB throwing to TE more, it is much more than just a young QB. You need to consider the offensive scheme the team runs and that individual QBs tendencies. The WR corp of the team also plays a factor.
Consider these 2004 rooks:
QB:Carson Palmer
Top TE: Matt Schobel
Caught 21 passes for 201 yards and 4 TDs
QB:Eli Manning
Top TE: Jeremy Shockey
Caught 61 passes for 666 yards and 6 TDs
QB:Big Ben
Top TE: Jerame Tuman
Caught 9 passes for 89 yards and 3 TDs
Big Ben and Palmer, both very solid QBs who had big rookie years, hardly used their TEs. I attribute this to the style of offense in Pitt and Cincy, the lack of quality receiving TEs, and their solid WR corps.
Manning, on the other hand, has a great receiving TE in Shockey and is in an offense that plans to look at Shockey....
So, it is more than just a young/rookie/inexperienced QB and a big TE......but, the niners do lack a solid WR corp (no Hines Ward or C.Johnson there) and do have a solid TE in Davis, so who knows....maybe he will have a huge season.
