You bring in Wisniewski and have a 3 man competition for RG & C. Best 2 men win, I think Wisniewski wins one of the spots. Also, Cooper could play C if need be so Shipley, Wisniewski and Cooper would make me happy with the interior line, C more specifically.
That's a fair analysis, but you're basically saying the loser will play Center. We may not even get Wis.
I'm not confident in that. Contract wise maybe, but Lyle has been with this line for a long time.
The idea of Cooper at Center depresses me frankly. It limits one of his best attributes, and one of the reasons I believe we drafted him, which is his athleticism and ability to pull across the line. So I believe you can eliminate him from Center contention.
I'm just not confident Shipley is better than Lyle. Change is nice, but not always best.
