Here is Ed's first Mock.
Ed Bouchettes Mock Is really good

1 Brandon Harris
2 Rahim moore
3 John Moffit
4 Alex Henery (k)
5 Austin Pettis
6 Anthony Grey 5'11" 330 lb DT/NT SMU
7 Monte Simons DE/OLB KENT

I'd Switch Pettis & Henery but this is nice.
I seen a few mocks that had us take Aaron Williams in the first & Ras I Dowling in the 2nd. They said with the idea that one will be groomed at Safety. Hot Dam I like his thinking. Fill or DB needs its long over due.
Trade out of first get extra 4th round pick,2 4ths or 3rd and get our Db's,OL & DL set. If we have the extra 3rd we can get Pettis & Moffit in the 3rd. Of course taking Pettis with the earlier pick or even grabbing Greg Little in the 2nd.

From Ed Bouchette
Here's my stab in the dark, based on some reading, some basic understanding of the Steelers' roster, and some rank speculation.

Round 1 -- Brandon Harris, CB, Miami -- Some say he doesn't get his head around fast enough and that he didn't pull in enough interceptions during his college career, but this underclassman has the athleticism, fluidity and instincts to be a top corner in the NFL. He excels in man and zone coverage, and he doesn't mind sticking his hat in the pile to tackle.

Round 2 -- Rahim Moore, S, UCLA -- Though some were disappointed with his slow 40 time at the combine, this kid has the ball skills and confidence to become the ball-hawking free safety that the Steelers have lacked for a long while. Ryan Clark ain't getting any younger, and a talented young safety would be a welcome addition to the defense.

Round 3 -- John Moffitt, OG, Wisconsin -- Just an excellent overall guard prospect who has the talent and smarts to compete with Doug Legursky to start at right guard in 2011. He has prototypical size at 6'4" and 319 lbs., while one scout described him as having the "phone booth quickness, mobility and footwork" to be a potential Pro Bowler at guard for years to come.

Round 4 -- Alex Henery, K, Nebraska -- Best kicking prospect in a couple of years, as his accuracy is off the charts (89.5% on field goal attempts for his career, an NCAA record) and his leg strength is excellent (he nailed two 50+ yard kicks in 2010 alone). He could be a big weapon for the Steelers.

Round 5 -- Austin Pettis, WR, Boise St. -- And the Steelers take another shot at that elusive "big receiver" that they can never seem to find. Pettis is 6'3" and a hard worker, so hopefully he can stick.

Round 6 -- Anthony Gray, DT/NT, Southern Mississippi -- He worked out for the Steelers in early April and, at 5'11" and 330 lbs., he fits the space-eating mold of Steeler nose tackles in the 3-4.

Round 7 -- Monte' Simmons, DE/OLB, Kent State -- Ray Jackson, the Steelers' director of player development, went to see Mr. Simmons work out at Kent State. And we all know the Steelers have a little luck with undersized 'backers from that school.
