Which team is better overall Detroit lions or oakland raiders?

i say Detroit lions even though they just came off a 0-16 season. i really like stafford they just drafted and calvin johnson is a big weapon for them at wide out. and well oakland ped up crabtree to get some speed guy at wr. i think as long as al davis is the owner of that team they are worthless. i think in oakland they draft on 40 times and thats it i dont think they even care about any thing else. in a couple of years i think Detroit will be good while oakland is standing still. and i dont like niether team im a texans fan and i think they are getting ready for lift off this year or next year but thats different.
