They clearly planned on Zadorov playing with Barrie because they didn't have any good fallback options, except another young question mark in Gormley, and then the old stop gap plan of Holden and Guenin, which they used the rest of the year.
They were planning on it early in camp, and it didn't look that good, and then they tried it again vs Anaheim I believe and it still didn't look good. Just like how they planned on Stuart playing with EJ, they quickly realized neither were capable at the time.
I'm not sure what Anaheim game you're talking about. Zadorov never spent an actual practice with Barrie once camp started. They were together during the informal scrimmages, but once the actual practices started with the team, Roy wasn't using them as partners. Gormley was with Barrie basically all through preseason and camp and Z was with a lot of different players, and Beauch and EJ were inseparable. I still remember Roy going on TV saying they think Gormley can be a top 4 guy for them this year, then blowing that up like 3 days later, right before the regular season started.
They may have planned for it in the summer, but it never happened in camp, so they must have changed their minds before they got on the ice. The only time it really happened was the Dallas and Boston games at the start of the year, and the Boston game was a disaster, so they never tried it again. I'm not sure it would have worked well, but Zadorov had a lot of different partners to start the year, and I don't think that helped with his play all that much. The Avs definitely didn't go into camp with much of a backup plan.
Barrie spent camp with Gormley, was with Guenin opening night, then with Zadorov for 1.5 games, then ended up with Holden for the rest of the year. Guy really needs to be given a good and stable partner. When people talk about Barrie not being worth the money, I just get a little confused because the guy has had to carry around anchors as his partner for 3 years now (Guenin and Holden).
