I don't think Ainge is even interested if you don't have a 6'8" wingspan regardless of height.
Here is a recap of the new draft class length.
#3 Tatum 6'11" wingspan
#37 Semi Ojeleye 6'6", almost 6'10" wingspan
#53 Kadeem Allen 6'1" PG 6'9.25" wingspan
#56 Jabari Bird 6'4" 6'8" Wingspan
Good thing Bird can really shoot, cause 6'8" is cutting it close.
Bradley be has a 6'7" wingspan he should be worried. Rozier and Smart are 6'8" and 6'9"
It's just crazy to me that even at 6'1" in height he finds the guys with the longest arms.
