Ibrox side Glasgow Rangers boss Mark Warburton has signed eight players this summer.
The 34-year-old defender has spent the last fortnight on trial with Rangers and played in their 2-1 pre-season friendly win away to Charleston Battery.
Recent reports from The Daily Record have indicated that Rangers might well leave South Carolina without the veteran centre-half - who has close to 70 caps for the United States during a 10-year international career - but Walsh believes he would bring plenty of experience to the side.
"Yeah he's a good guy, obviously an exprienced player," Walsh told Rangers TV. "If he signs then that's just another experienced player for Rangers. He has 69 caps for America so that's obviously a lot of experience which could come into the team."
Rangers have signed no fewer than eight players so far this summer, with Jordan Rossiter, Joey Barton, Clint Hill, Josh Windass, Matt Crooks, Niko Kranjcar, Matt Gilks and Lee Hodson signing on the dotted line with the Glasgow giants so far.
They have done some excellent business, to be fair, but it still remains to be seen how well they do next season. Fans will be expecting a Scottish Premiership title challenge. At a club like Rangers, that has to be the ambition regardless of the fact it'll be their first season back.
