I agree with that assessment. In years past, we often had incoming transfers with proven numbers at their old schools. Examples from last year (Youngblood - co-AAC player of the year at USF, Mallette - 15 ppg at Pepperdine, Clifford - 3 bbg/10 ppg), two years ago (Nelson - 18 ppg at North Dakota, Estrada - 20 ppg/CAA player of the year, Wrightsell - 16 ppg at CS-F), and three years ago (Sears - 20 ppg at Ohio, Welch - 12 ppg at St. Bon).
This year, Williamson (Patriot League player of the year) is the only guy who really fits that mold of being that proven performer. Bristow (WAC Frosh of the Year, 11 ppg), Bethea (7 ppg at UM), and Bowen (8 ppg/1.5 bpg at FSU) all SEEM to be a step down from that caliber of a player and instead come with a perceived unrealized upside that's more in the mold of Holloway, Quinerly, and Burnett. Obviously, we've had those types of guys pan out in the past and hopefully this year's group will also. However, add in the injury concern and unknown of incoming recruits and it's completely fair to say they're "unproven" at this point.
