I know that in the past, they've even selected linemen in the 2nd round. But in point of fact, the best guys they have on the Oline have come via FA and trade for low picks. Snead has even spoken about this.
So I expect their 2nd round and even 3rd round picks to be offensive and defensive play making positions.
They're good at RB, so forget it. I think they think they're good at TE. If they can just keep the guys they have on the Oline, they don't need to draft anyone high there.
So, to me, assuming that Snead continues the pattern and won't address QB, it's going to be WR, Secondary (almost certainly CB because they have Safeties coming out their ears) or edge rusher. Naturally, he will always leave himself open to someone they covet that perhaps they assumed would be gone by the time their turn arrived.
