Swanson and Laken need to grow and get better. Period. Inexperienced and need to add muscle. Reiff and Warford are good though Reiff even with the terrible start this year (pass pro first 3 for Reiff). We need a right tackle if Waddle continues to play like this and get hurt all the time.
Plenty of weapons and Stafford is good. He needs average run support and protection though. 2.6 YPC and 39% pressure is terrible but this may be due to young players and injuries.
Defense they have Ansah, Slay as the building blocks. Levy and Quin have plenty of years left. Ihedigbo, Jones are good/solid but must be replaced next year. Could see them back on one or two year deals though.
Ngata is a good player for us so far. These injuries freaking suck thouhg. Of course he's healthy all the time with Ravens but gets hamstring and calf injuries early in Detroit (typical bullshit). He has 2 years left but they need to work out a deal there. Wright and Reid can grow into number 2 and 3 DT contributors. Both young.
LB Tulloch is done. 6 million in cap room when we cut him. That makes room for a good free agent. Whitehead and Bynes and Travis Lewis look like they can easily replace Tulloch though. Lewis and Whitehead are free agents though but should be cheap. We'll see how they finish the year.
We need a new power back with Bell's issues. We'll see what Zenner does too. Loving Abudullah despite the lack of blocking for him.
So really RT, LE, CB (Mathis though he rebounded after a bad Week 1) and ILB (maybe depending on Lewis/Whitehead). CB depends on Alex Carter too. Diggs and Lawson must grow at nickel back.
The Lions will have a good amount of cap room and have extra picks in the draft with the comp picks and trades made.
