Dante Rosario

No player has been more impressive in Denver Broncos camp than rookie tight end Julius Thomas.

The fourth-round pick has great athleticism and has impressed coaches with his ability to make plays all over the field. Thomas has lined up on the line, in the slot and outside, and has been effective in all three spots.

He still needs to improve his blocking, a reason the team added veterans Daniel Fells and Dante Rosario in free agency.

Tight end is a deep position this year, and Denver will likely be more of a running team under new head coach John Fox. Thomas won't find his way onto many redraft league rosters, but he could be someone for dynasty owners to keep an eye on.
