Wahington Redskins Draft a Mistake or Not?

Now as the Washington Redskins come into the 2010 NFL draft they selected their 1st round draft pick at number 4 Trent Williams Offensive Tackle 6'5" and 315 pounds from the college of Oklahoma. Now that is an excellent choice in fact they needed an OL. They also needed a QB but then again they got Donovan Mcnabb, but thats not going to last long so maybe a possibility of Colt Brennan will be the superbowl QB coming into the game later on who know.

You See in this draft the Washington Redkins also needed a safty, Corner, and a Defensive Line. They could of got alot of them if they traded their 1st round draft pick for either 2 second rounders and a 6 or 2,3,3. Coming into this draft they had only 6 picks a 1,4,6,7,7,7 these were their picks. and they drafted a OT, LB, TE, WR, C, and another OT. Now im not saying these are bad picks, but im saying i think they could of got a lot more from the other picks. So would you say their draft was a mistake or Not?
