From NFL.com:
Kindle is a two-year starter for the Longhorns as a defensive end but many will try and project him to outside linebacker in the NFL. He has a good combination of length and athleticism but lacks the bulk needs to be an effective run defender at the next level. He has been a disruptive force penetrating the line of scrimmage in the Longhorns 4-3 front. Kindle runs well but doesn?t have elite speed or range for a stand up player and will need lots of work developing his coverage techniques and awareness. He is inconsistent using his hands to maintain leverage on his opponent and will need to improve in this area both as a pass rusher as well as run defender. Kindle does play hard and has a frame to add at least 20 pounds, which bodes well for his potential as a special team?s contributor as well being utilized as a backup linebacker or edge rusher in sub packages.
From Gil Brandt: (had Kindle in 4th tier)
Outstanding athlete who was named high school player of the year for both offense (as a running back) and defense, something that had never been done in modern history. He can rush the passer or drop into space. Was outstanding vs. Alabama in the BCS title game.
