Being a lifelong Browns fan and an NFL jersey collector, I was watching these jerseys the entire auction. As for the prices, here is my take....

Thomas-good pro bowl lineman. Most linemen jerseys sell for much less.

Lewis-10,000 yard rusher(I collect these)1 time pro bowler, 2000 yard season. But not a glamour runner. Power back. About what I thought it would go for.

Cribbs-8 return tds. Most ever in only 5 years. But yes, a returner. Is a great player to watch. Most likely to be incorporated more in the offense next year. Actually thought it would have gone higher.

Dawson-Longest tenured Brown. Very reliable kicker throughout his career. But kickers jerseys don't usually garner much. About what I thought it would go for.

In essence, I think the Lewis and Cribbs went for good prices. I think the Thomas was a bit high and the Dawson at what I expected. Just my take.
