I don't see anyone giving up future #1s with the cap likely coming, and the Steelers 2nd rounder is too late to likely warrant one.
How about this scenario...
Steelers trade their 2nd rounder (#52) and 6th rounder (#188) to Cleveland for their two third rounders (#71 and #85.)
Then, Steelers trade their 4th and 2 non-comp fifths (#116, #151, and #155) to Indy for their 3rd rounder (#94.)
Of course it takes two to tango, but the pick values match up on the chart. End result :
Instead of having a 2nd, 3rd, 4th, 4 5ths, a 6th and a 7th.. we now have no 2nd, 4 3rd rounders, no 4th, 2 fifths, no 6th, and a 7th. Using draft simulators, available (and likely to be drafted by PIT) players that would be changed are (trying to match positions for easier comparison):
Staying put : Golden Tate (WR) in the 2nd, Brandon Spikes (ILB) in the 3rd, Walter Thurmond (CB) in the 4th, LeGarrette Blount (RB), Clifton Geathers (DE), George Selvie (OLB), Sam Young (OT) in the 5th, Nate Byham (TE) in the 6th and Sam Shields (CB) in the 7th.
Making the deals : Damian Williams (WR), Brandon Spikes (ILB), Amari Spievey (CB), Joe McKnight (RB) in the 3rd, Clifton Geathers (DE), George Selvie (OLB) in the 5th, and Matt Kopa (OT) in the 7th.
They'd take a hit in quality at WR, get no TE, get a lower-upside guy at OT. That's the downside. Upside is, they'd get a pretty solid upgrade at CB and RB.
