You don't think Solomon-Simmons is a reputable attorney? You think Parrish takes on a case thinking it wouldn't have resources to win? Iowa is worried. Maybe I actually do know what I'm talking about here
Everyone is just speculating, me include. To answer your first question, it is a one man shop out of Tulsa that seems to specialize in race related representations (including personal injury), but I am not finding much of anything on large settlements where he was lead counsel, trials, etc. That is something plaintiffs' attorneys always promote for obvious reasons. Maybe he is extremely humble. To the players benefit,
anyone, would be a step up from the Green character that was speaking on their behalf previously.
Mr. Parrish does have a reputation and is good at knowing how to get in the media and get his name out there. Sometimes that benefit is worth taking on a case with some thorns. This one absolutely has $ problems, all these type of cases do, which is why the ones with a lot of merit get snapped up by the most well funded plaintiffs' firms from around the US. Maybe they can go to a litigation funder, but those have steep rates and difficult criteria for approval.
I had a case for a college where the plaintiffs' alleged a certain program was "too hard", not joking. This somewhat reminds me of that. Only reason it is getting some publicity is b/c they have this racial issue, which seems overblown. For credibility they need a lot of players that actually stayed 4-5 years as plaintiffs, not guys that did not play and left.
