These stats are going to be very simple due to lacking completion %, the various QB ratings, and other "advanced" stats. What these stats do clearly show is the Win/Loss record for these young QBs. Also, this post does not include each QB's rushing stats - a big part of the value of Newton and Tebow.
First a comparison of QBs drafted in 2011. These simple stats only consider games started.
Blaine Gabbert (JAX; rookie year); 3-8 (round 1, 10th pick)
Christian Ponder (MIN; rookie + 1 game of 2nd year); 3-8 (round 1, 12); playoffs 2012
Andy Dalton (CIN; rookie year); 7-4 (round 2, 35); playoffs both years
Cam Newton (CAE; rookie year); 3-8 (round 1, 1)
Colin Kaepernick (SF; 2nd year); 5-2 (round 2, 36)**** NOT 11 STARTS***** playoffs 2012
TJ Yates (HOU; rookie year); 2-3 (round 5, 52)****NOT 11 STARTS***** playoffs 2011
Now to QBs drafted in 2012. (All are rookies, obviously.)
Andrew Luck (IND); 7-4 (round 1, 1); playoffs
Robert Griffin III (WAS); 5-6 (round 1, 2); playoffs
Ryan Tannehill (MIA); 5-6 (round 1, 8)
Brandon Weeden (CLE); 3-8 (round 1, 22)
Russell Wilson (SEA); 6-5 (round 3, 75); playoffs
Now let's go back to 2010. Again, only the first 11 starts count.
Sam Bradford (STL; rookie year); 5-6 (1,1)
Tim Tebow (DEN; 3 rookie, 8 2nd year); 8-3 (1, 25); playoffs 2nd year
Jimmy Clausen (CAR; rookie); 1-9 (2, 48) ****NOT 11 STARTS*****
Colt McCoy (CLE; 8 rookie, 3 2nd year); 4-7 (3, 85)
John Skelton (ARI; 4 rookie, 7 2nd year) (5, 155) [one really good game doesn't count for him due to not starting]
This post can be expanded to include more "young" QBs. 2009 include the following players: Stafford, Sanchez, Freeman and Painter all with extended starting experience. 2008 has: Ryan, Flacco, and Henne. 2007 was a horrid year for QBs: J. Russell, Quinn, Kolb, Beck, Stanton, Edwards, Troy Smith and Thigpen all getting starting experience.
If anyone wants to add to this post with career QB "advanced" stats, feel free. Always keep in mind that each player is part of a team. It can be pretty difficult to separate the performance of one player from that of his teammates, coaches, and game conditions/situations. Sanchez making it to two AFC Championships should be the clear example. On the flip side of that coin are the results from RG3 and Luck that turned two bad teams into playoff participants.
My personal opinion is that Locker is project and his ceiling is somewhere in the middle of the NFL QBs. He can definitely help this team win games, but it will be more on the TEAM part of it than simply him "willing" the Titans to victory. With that said, I would think a better OL and some BIG additions to the defense are what will most help the team going forward. Leadership is especially something the D needs.
