Well judging by his performance against Arsenal, Bentley wouldn't be much use for Spurs's youth team.
Dawson, Gomes and Defoe are big misses. I do find it strange that you're bemoaning Woodgate, King and Gallas being injured.
Woodgate's on the verge of retiring, King obviously can't play every 3 days and Gallas was very injury prone at Arsenal so not sure why you're surprised they're all injured.
Few Spurs fans I know think the main problem is they don't have a striker who really excels playing as a lone striker. Both Crouch and Pav can both do it up to a point but neither are Torres or Drogba standard.
